3-Methylaminopropylamine

3-Methylaminopropylamine (CAS 6291-84-5), commonly abbreviated as MAPA, is a bifunctional diamine used as a reactive building block and process chemical.

Where is 3-Methylaminopropylamine used?

• Water treatment: pH buffer and chelating agent in scale inhibitor and corrosion control formulations
• Polymer manufacturing: chain initiator or crosslinker
• Specialty resins and polyamide-based materials
• Agrochemical synthesis: intermediate in the preparation of active ingredient molecules
• Pharmaceutical production: synthetic intermediate for APIs and drug delivery compounds
• Its primary and secondary amine groups initiate polymerization, regulate pH and form stable chelate complexes.

Good to know: Technical grade is the standard commercial offering, with purity typically 98% or higher by GC analysis; pharmaceutical-grade material is available from select manufacturers. High-purity orders require CoA, residual solvent testing and batch traceability.

Commercial specifications
