When purchasing high-purity chlorinated solvents, buyers are usually more concerned with more than the nominal purity value. Trace moisture, residual chlorine, heavy metals, appearance, batch-to-batch consistency, and documentation can all affect downstream processes. AOLANSU supplies high purity 1,2-Dichloroethane with controlled impurity levels and stable specifications for applications where raw-material consistency is more important than simply reducing solvent cost.
Produced in our China facility, this material is refined through controlled purification and rectification processes. The product reaches 99.8%–99.9% purity by GC detection, with moisture controlled at ≤0.005%. Its colorless transparent appearance, stable physical properties, and strong solvency make it suitable for pharmaceutical intermediates, electronic materials, precision chemical synthesis, and other applications requiring tighter raw-material control. AOLANSU also holds a hazardous chemicals business license and provides the relevant documentation required for compliant industrial procurement.
For high-end chemical processes, a specification such as “99.8% purity” does not provide the complete picture. Two materials with similar assay results may behave differently if their moisture or trace impurity profiles are different. For this reason, buyers should evaluate the complete specification together with the actual process requirements.
For applications sensitive to water, our product provides a moisture specification of ≤0.005% measured by the Karl Fischer method. Trace heavy metals and free chlorine are also controlled at low levels, helping reduce the possibility of unwanted interference in sensitive synthesis, cleaning, or purification processes. Each batch can be supported with quality documentation so purchasing and production teams can verify the material before use.

In precision chemical synthesis, the main purchasing concern is often reaction consistency. A controlled impurity profile can help manufacturers reduce unexpected variation between production batches. With high purity and low moisture, this material can be considered for synthesis processes where solvent quality directly affects reaction control and downstream purification.
For pharmaceutical intermediate manufacturing, raw materials are normally evaluated according to tighter quality-control procedures than those used for general industrial solvents. The low moisture specification and controlled trace impurities make this material suitable for processes where solvent composition needs to remain consistent. Customers can review batch-specific quality documents before incorporating the material into their production system.
Electronic-material applications have another requirement: surface cleanliness. When used as a cleaning or processing solvent, residual contaminants can become a source of product variation. Its strong solvency and controlled impurity profile make it suitable for selected electronic-component cleaning and electronic-material preparation processes where residue control is important.
For high-purity organic reagent preparation and specialty chemical processing, the purchasing decision can also depend on repeatability rather than the lowest initial purchase price. Consistent specifications from batch to batch can simplify incoming inspection and reduce the need for frequent process adjustments.
A German pharmaceutical intermediate manufacturer specializing in antibiotic intermediates has strict requirements for solvent purity and trace impurities. After evaluating several suppliers, the company selected AOLANSU material for its production process, with a monthly purchasing volume of approximately 150 tons.
The product maintained purity consistently above 99.8% and provided controlled impurity levels suitable for the customer's quality-control requirements. The cooperation has continued for three years, with the customer recognizing the consistency of product specifications and delivery performance.
A South Korean electronic-material manufacturer uses this material as a cleaning solvent for electronic components. The company required strong dissolving capability while minimizing residual contamination that could influence component performance.
After introducing the product into its cleaning process, the customer's electronic-component qualification rate increased by 15%. Following the successful evaluation, AOLANSU became a designated supplier for the customer, demonstrating the importance of solvent consistency in precision electronic manufacturing.
For buyers operating continuous production lines, changing solvent specifications can create additional validation work. Even when the nominal purity remains within specification, variations in moisture or trace impurities may require adjustments to reaction conditions, cleaning cycles, or downstream purification.
AOLANSU focuses on specification consistency throughout production and shipment. The product is tested according to defined quality parameters, while supporting documents such as COA and MSDS can be provided for procurement review. This approach allows customers to establish clearer incoming-material standards and reduce uncertainty when switching from trial quantities to regular supply.
Different buyers have different qualification procedures. Customers evaluating a new solvent can begin with a small quantity for laboratory or process verification before moving to regular industrial procurement. For qualified production applications, larger-volume orders can be arranged according to the customer's consumption schedule and packaging requirements.
Standard industrial packaging and customized packaging solutions are available depending on the order volume, transportation requirements, and customer's receiving facilities. For international orders, AOLANSU can provide relevant commercial and compliance documentation to support customs clearance and hazardous-chemical logistics.
For international chemical procurement, product quality is only one part of the purchasing decision. Buyers may also need documentation for supplier qualification, incoming inspection, transportation, customs clearance, and internal safety management.
AOLANSU can provide COA, MSDS, and relevant export documentation according to the order and destination requirements. As a supplier of hazardous chemicals, the company operates with a hazardous chemicals business license and works with qualified logistics partners for compliant transportation. Customers can also request product samples and technical information before placing larger orders.
The main difference is the degree of impurity control. Standard industrial-grade material may be sufficient for general-purpose applications, while high-purity material is intended for processes where moisture and trace contaminants can influence product quality. This product provides 99.8%–99.9% purity, moisture ≤0.005%, heavy metals ≤0.000002%, and free chlorine ≤0.00003%, making it more suitable for applications with tighter raw-material specifications.
Yes. AOLANSU supports sample evaluation before regular procurement. Buyers can use the sample to verify compatibility with their existing formulation, synthesis, cleaning process, or quality-control requirements before moving to larger-volume purchasing.
COA and MSDS can be provided together with relevant export and customs documentation according to the order requirements. Buyers can use these documents for supplier qualification, incoming inspection, hazardous-material handling, and customs-clearance procedures.
High Purity 1,2-Dichloroethane is a hazardous chemical and requires controlled storage and transportation. It should be kept in a cool, dry, well-ventilated area away from ignition sources and incompatible materials. Handling personnel should follow the applicable MSDS and local hazardous-chemical regulations and use appropriate protective equipment. International shipments should be arranged through qualified dangerous-goods logistics providers.
For buyers who need more than a nominal purity specification, AOLANSU provides a controlled supply solution focused on impurity management, batch consistency, documentation, and international delivery. Our high purity 1,2-Dichloroethane is available for laboratory evaluation, process validation, and long-term industrial procurement.
With a hazardous chemicals business license, professional quality-control procedures, export support, and experience serving pharmaceutical and electronic-material customers, AOLANSU can provide a practical procurement solution for customers with demanding solvent specifications.
