Description
3-Methoxypropylamine (CAS 5332-73-0), commonly abbreviated as MOPA, is a primary aliphatic amine with the molecular formula C4H11NO. It is also referenced under the names 3-Methoxy-1-propanamine and gamma-Methoxypropylamine. No E-code designation applies to this substance.
In polymer and coatings formulations, MOPA functions as a crosslinker and curing agent by reacting with epoxy or isocyanate groups to build network structures. In personal care applications, it acts as a pH buffer and skin conditioner by neutralizing acidic components and stabilizing formulation pH. Its antioxidant activity also supports shelf-life protection in food-contact and nutritional contexts.
MOPA is supplied under REACH registration and is available in technical and formulation-grade qualities suited to polymer, cosmetic, and food-adjacent applications. Standard packaging includes drums and IBC containers. Procurement teams should confirm grade-specific purity specifications and SDS documentation prior to sourcing.
