English description（英文原文，共 1068 字符）
Product Name:Dimethyl Tetrachloroterephthalate
English Name:Dimethyl Tetrachloroterephthalate
CAS No.:20098-41-3
Aliases:DCPA, Tetrachloroterephthalic acid dimethyl ester, Chlorthal-dimethyl
Molecular Formula:C10H6Cl4O4
Physical Properties:White crystalline powder, melting point 150-156°C, boiling point approximately 381°C (760 mmHg), relative density 1.58 g/cm³, low vapor pressure. Insoluble in water, slightly soluble in alcohols, readily soluble in acetone, benzene and other organic solvents. Chemically stable, resistant to hydrolysis under both acidic and alkaline conditions, with good light stability.
Uses:Chlorthal-dimethyl is a selective pre-emergence herbicide used primarily to control grass weeds and certain broadleaf weeds in cotton, soybean, peanut and other crop fields. Its mechanism of action involves inhibiting cell division and protein synthesis during weed seed germination.
Technical Specifications:
Content ≥ 95.0%
Melting point 150-156°C
Water content ≤ 0.5%
Residue on ignition ≤ 0.2%
Particle size (through 44μm sieve) ≥ 95%
