N,N-Dimethylbenzylamine (BDMA), TCI D0688

• A tertiary amine catalyst: N,N-Dimethylbenzylamine, commonly abbreviated BDMA or DMBA, is a tertiary amine used chiefly as a catalyst and accelerator. It is best known as an accelerator for the curing of epoxy resins and as a catalyst in polyurethane foam systems, and it also serves as a reagent in organic synthesis. In each role it drives or speeds a reaction without being consumed as a primary reactant, which is what makes tertiary amines like BDMA so useful in industrial chemistry.
• Role in epoxy and polyurethane systems: In epoxy formulations, BDMA promotes the curing reaction, allowing faster or lower-temperature cure, which can improve throughput and enable processing of parts that cannot tolerate high heat. In polyurethane foam systems it acts as a catalyst that influences the balance and rate of the reactions that form the foam. Formulators add it in carefully controlled amounts, following the guidance for their specific resin or foam system to achieve the desired cure profile and final properties.
• Verified identity and purity: This TCI product (catalog D0688) is a minimum 98.0% (GC) grade, CAS number 103-83-3, with molecular formula C9H13N and molecular weight 135.21. It is a colorless to almost colorless clear liquid; synonyms include N-benzyldimethylamine, BDMA, and DMBA. Confirming these identifiers ensures the correct amine is used, which matters because catalyst identity and purity directly affect cure behavior and end-product quality.
• Hazards and safe handling: BDMA is a flammable, corrosive amine that is toxic if swallowed and can cause severe skin burns and eye damage, so it demands careful handling. It should be used with appropriate protective equipment and adequate ventilation, kept away from ignition sources, and stored per the manufacturer's guidance. The Safety Data Sheet should be reviewed before use, and the product carries a California Prop 65 warning that should be noted during handling and storage.
