CAS NO.	79-37-8
Formula & Weight	C2Cl2O2 (MW: 126.93)
Chemical Structure
Technical Specifications	Appearance: Colorless or light yellow fuming liquid Purity (GC): ≥ 99.0% Phosphorus Trichloride (PCl3): ≤ 0.3% Phosphorus Oxychloride (POCl3): ≤ 0.6% Boiling Point: 63-64°C
Key Applications	A versatile reagent for critical synthesis: 1. Agrochemicals (Herbicides & Insecticides) Key intermediate for Benzoylurea insecticides (e.g., Flumuron, Hexaflumuron). Essential for Sulfonylurea herbicides (e.g., Metsulfuron-methyl, Chlorsulfuron, Bensulfuron-methyl). 2. Pharmaceutical Synthesis Used in the synthesis of broad-spectrum antibiotics. Swern Oxidation: The gold standard reagent for activating DMSO to oxidize alcohols to aldehydes/ketones under mild conditions. 3. Advanced Materials Acylation agent for high-performance polyamide synthesis. Precursor for chemical luminescent materials (glow sticks).
Safety & Handling	Store in a cool, dry, well-ventilated area under inert gas. Wear full protective gear including respirator and chemical-resistant gloves. Corrosive/Lachrymator: Avoid all contact with skin, eyes, and clothing.
