Cyclopropylamine

Cyclopropylamine (CAS 765-30-0, EC 212-142-2, formula C3H7N) is a primary aliphatic amine also referred to as aminocyclopropane or aminotrimethylene. It carries no assigned E-code and is classified under HS code 29213099 within the broader amines category.

In pharmaceutical synthesis, cyclopropylamine serves as a building block for introducing the cyclopropylamino motif into active ingredients, where the strained ring modulates metabolic stability. In polymer chemistry, it functions as a crosslinker by reacting with epoxide or isocyanate groups to form covalent network structures, directly influencing mechanical and thermal performance of the cured material.

Cyclopropylamine is supplied at 98% purity as a volatile liquid and falls under REACH registration requirements for European procurement. Buyers should confirm SDS compliance and confirm packaging formats, typically small drums or IBC, with the supplier prior to order placement.
