What is N,N-Dimethylbutylamine?
N,N-Dimethylbutylamine (CAS 927-62-8), commonly abbreviated as DMBA, is a tertiary aliphatic amine used in chemical manufacturing as a catalyst, pH regulator, and solvent carrier.
Where is N,N-Dimethylbutylamine used?
- Pharmaceutical manufacturing: intermediate in the synthesis of active ingredients
- Pharmaceutical manufacturing: neutralizing agent in salt formation steps
- Polymer and resin production: catalyst in polyurethane and epoxy cure systems, where controlled amine activity influences reaction rates
- Agrochemical formulation: production of herbicide and pesticide intermediates requiring a tertiary amine base
- Water treatment chemicals: pH-buffering agent
- It is a practical building block and process chemical in synthesis-driven industries.
Good to know: Pharmaceutical-grade supply is obtainable from select manufacturers where documented purity specifications are required; batch traceability is maintained for GMP-compliant processes.
Commercial specifications
- Drums and IBC containers suited for industrial volumes
