  • Applications

    1-Pyrrolidineethanamine (CAS 7154-73-6) is a bifunctional amine that serves primarily as an intermediate in the synthesis of small-molecule pharmaceuticals, acting as a versatile building block for amine-functionalized scaffolds. It is also used as an intermediate in agrochemical development, and in fragrance chemistry as a fragrance/intermediate for aroma compounds. In polymer and coatings formulations, it can function as a curing agent or crosslinking component for epoxy and polyurethane systems. Additionally, it is used as a versatile reagent in chemical synthesis, serving as a precursor to other amine derivatives in fine chemicals. Its exact use is application-specific and subject to local regulations and formulation limits.
