1,2-Dichloroethane CAS 107-06-2

Ethylene Dichloride (EDC) Technical Grade

The technical-grade specification below is based on ASTM D5960-03(2023). We guarantee supply quality against the specification and test methods agreed in the order.

• CAS: 107-06-2; EC: 203-458-1
• Molecular formula: C₂H₄Cl₂; molecular weight: 98.96 g/mol
• Appearance: clear, colourless liquid
• EDC assay: ≥99.8 wt%; quantitative GC method validated under ASTM D6806
• Water: ≤200 ppm; Karl Fischer titration, ASTM D3401
• Acidity, as HCl: ≤10 ppm; ASTM D2989
• Colour: ≤10 Pt-Co; ASTM D2108
• Specific gravity at 25/25 °C: 1.248–1.252; ASTM D2111

We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS), plus a GC report or chromatogram and Karl Fischer water results for the quoted grade. The GC assay is calculated by subtracting quantified organic impurities and stabilizers from 100 wt%; an uncorrected GC area percentage is not the same result. Water is measured and reported separately.

Applications and process-solvent selection

EDC is a feedstock for vinyl chloride monomer (VCM), which is polymerized into polyvinyl chloride (PVC). EDC feedstock specifications and PVC resin grades cover different stages of this chain. Selected industrial uses also include adhesive and sealant formulations and process-solvent applications in chemical synthesis; these require suitable process controls and compliance with the rules for the intended use and destination.

For chlorinated process-solvent sourcing, compare EDC with dichloromethane (DCM) by the required water limit, stabilizer system and process compatibility. An industrial assay specification alone does not establish an anhydrous or application-specific grade.

For metal-cleaning process comparisons, trichloroethylene (TCE) and perchloroethylene (PCE) require their own suitable grades, stabilizer systems and equipment conditions. EDC has different flammability and handling characteristics. These solvents are comparison options, not automatic drop-in replacements.

Steel-drum and bulk supply

250 kg net in EDC-compatible steel drums is offered; bulk tank delivery can be arranged for the order. Containers and transfer equipment must be compatible with EDC. Keep containers tightly closed in a cool, dry, well-ventilated area, away from ignition sources, and prevent water or moist air from entering. The supplied-grade SDS sets out the handling and storage requirements.

Send the quantity, destination and intended process for a quotation. Include any plant specification or tighter water and impurity limits; the quotation will state the agreed grade, packing and net loading.
