Allylamine

Allylamine, also called allyl amine, IUPAC name 2-propen-1-amine, is an organic compound that features a vinyl group (CH2=CH–) attached to a primary amine (–NH2). Its molecular formula is C3H7N. In typical lab and industrial settings it is encountered as a colorless liquid with a sharp, amine-like odor. The molecule combines a reactive double bond with a basic amine, making it versatile in chemical synthesis. It is soluble in many organic solvents and is moderately soluble in water.

Allylamine is primarily used as a chemical building block in organic synthesis. It serves as a precursor to N-allyl derivatives and to various polymers and resins that incorporate allyl functionality. The vinyl group allows addition reactions, while the amine can be leveraged for further functionalization or salt formation, enabling a range of downstream products in pharmaceuticals, agrochemicals, and materials chemistry.

Safety and handling are important considerations. Allylamine is a corrosive, toxic substance that can irritate skin, eyes, and the respiratory tract. It is flammable and should be handled in a well-ventilated area or fume hood with appropriate personal protective equipment. It can polymerize exothermically, so stabilizers or inhibitors are often used in storage. It should be kept away from oxidizers and stored in accordance with relevant regulations and guidelines.
