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 across multiple industrial sectors. Its combination of primary and secondary amine groups makes it effective for initiating polymerization, regulating pH, and forming stable chelate complexes in formulated systems.

In water treatment, MAPA functions as a pH buffer and chelating agent in scale inhibitor and corrosion control formulations. Polymer manufacturers use it as a chain initiator or crosslinker. It is utilized in the production of specialty resins and polyamide-based materials. In agrochemical synthesis, it serves as an intermediate in the preparation of active ingredient molecules.

These molecules require a methylated diamine backbone for stability. Pharmaceutical producers rely on MAPA as a synthetic intermediate for APIs and drug delivery compounds where reactivity is critical. Controlled amine reactivity is essential to process yield in these applications. 3-Methylaminopropylamine is supplied as a clear to slightly yellow liquid in drums and IBC containers.

Technical grade is the standard commercial offering, with purity levels typically at 98% or higher confirmed by GC analysis. Pharmaceutical-grade material is available from select manufacturers. Documentation requirements such as CoA, residual solvent testing, and batch traceability apply to these high-purity orders to ensure compliance with global manufacturing standards.
