3-methoxypropylamine
Description
3-Methoxypropylamine (CAS 5332-73-0), also known by the abbreviation MOPA, is a primary aliphatic amine used as a reactive intermediate and curing agent across specialty chemical manufacturing.
Its amine functionality makes it a building block for synthesizing active pharmaceutical ingredients, polymer additives, and surface-active compounds. In epoxy coating and resin systems, it acts as a curing agent.
This chemical contributes to controlled cure rates and improved film flexibility in various industrial applications. Pharmaceutical manufacturers use it as a key intermediate in synthesizing APIs and agrochemical compounds.
It is particularly useful where a primary amine with an ether spacer is required for molecular architecture. In personal care formulations, it functions as a pH buffer and stabilizer in rinse-off and leave-on products.
Precise alkalinity control is critical to formulation stability in these applications. Polymer producers also incorporate it as a chain modifier or reactive diluent to tune mechanical properties in specialty resin systems.
The product is supplied as a clear liquid in standard drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers. Technical grade is the primary commercial specification.
Purity levels are typically at 99% or higher confirmed by GC analysis. Certificates of Analysis covering purity, water content, and amine value are standard documentation for procurement and QA purposes.
