Description
N-Methyl-1,3-propanediamine (CAS 6291-84-5, EC 228-544-6) is a difunctional aliphatic diamine supplied as a clear liquid under trade designations including RARECHEM AL BW 0071 and commonly referenced as methylaminopropylamine or MAPA. It carries no assigned E-code and is classified under HS code 29212900.
In epoxy curing systems, its primary and secondary amine groups react sequentially with epoxide rings, enabling controlled crosslink density in polymer networks used in coatings and adhesives. It also serves as a reactive intermediate in agrochemical synthesis and functions as a pH buffer and chelating agent in water treatment formulations, where its amine groups coordinate with metal ions to prevent scale formation.
This material is available in technical and high-purity grades and is registered under REACH. Standard packaging includes drums and intermediate bulk containers, with documentation including SDS and CoA supplied on request. Buyers should confirm grade specifications against applicable regional chemical inventory requirements before procurement.
