Overview

(1,2-dibromo-2,2-dichloroethyl) dimethyl phosphate (CAS 300-76-5) is an organophosphorus compound with flame retardant and biocidal properties. This halogenated phosphate ester represents a specialized chemical intermediate combining both bromine and chlorine substituents with a phosphate group, resulting in unique thermal stability and fire suppression characteristics. The compound's molecular structure, featuring multiple halogen atoms and a dimethyl phosphate moiety, provides enhanced flame retardancy through both gas-phase and condensed-phase mechanisms. With its molecular formula C4H7Br2Cl2O4P and molecular weight of 380.78 g/mol, this substance exhibits properties typical of heavily halogenated organophosphorus compounds. The compound is classified under ADR transport class 6.1 and carries GHS07 and GHS09 pictograms, indicating acute toxicity hazards and environmental concerns. Safety considerations include potential skin and eye irritation, acute toxicity risks, and significant aquatic toxicity. Unlike simpler halogenated compounds such as chloromercury, this organophosphate structure provides dual-action flame suppression while maintaining chemical stability under processing conditions. Primary industrial applications include flame retardant formulations for textiles, plastics, and electronic components where superior fire resistance is required. The compound also finds use in specialized polymer additives and as an intermediate in the synthesis of other flame retardant systems. Additional applications may include biocidal formulations where both antimicrobial activity and thermal stability are essential. This technical-grade organophosphorus compound is available through OYSI's European distribution network, with full regulatory documentation and safety data sheets provided to support industrial applications.
