Dimethyl Methylphosphonate (DMMP)
Dimethyl methylphosphonate (DMMP) is a non-halogenated organo-phosphorus compound with the chemical formula CH3PO(OCH3)2, classified under HTS 2931.41.00.00 as a specific organo-inorganic derivative. It is a colorless liquid used primarily as a flame retardant additive and chemical intermediate.
99% Pure DMMP Flame Retardant Grade
High-purity (99%) dimethyl methylphosphonate is a key flame retardant precursor for polyurethane foams and textiles, fitting HTS 2931.41.00.00 due to its specific organo-phosphorus structure without halogens. It serves as a stable, low-toxicity intermediate in polymer manufacturing.
Industrial DMMP Chemical Intermediate
Dimethyl methylphosphonate in industrial bulk packaging is used as a phosphorylating agent in pharmaceutical synthesis and pesticides, precisely matching HTS 2931.41.00.00 for non-halogenated organo-phosphorus compounds. Its role as a building block ensures classification as a separate chemically defined compound.
DMMP for Polyurethane Foam Production
Specialty dimethyl methylphosphonate grade optimized for reactive flame retardancy in flexible polyurethane foams, classified under HTS 2931.41.00.00 as it remains a pure non-halogenated organo-phosphorus derivative. It reacts during foam polymerization without altering its chemical identity.
