2propen1amine

2-Propen-1-amine, commonly known as allylamine, is an organic compound with the formula C3H7N. Its structure features a vinyl group (CH2=CH−) attached to a primary amine (−NH2), giving the formula CH2=CH−CH2−NH2. It is a colorless liquid at room temperature that is miscible with water and many organic solvents. As a primary alkenyl amine, allylamine is reactive and tends to polymerize if not stabilized.

Allylamine is produced industrially as an intermediate in the synthesis of various chemicals. It is a versatile building block for organic synthesis and is used to prepare polymers such as poly(allylamine) and related derivatives. Poly(allylamine) and its cationic derivatives are used in water treatment as flocculants and in chromatography as ion-exchange materials. It can undergo typical amine chemistry, including acylation, amidation, and formation of Schiff bases with aldehydes.

Allylamine is a corrosive, irritant, and potentially toxic substance. It can irritate the skin, eyes, and respiratory tract and should be handled with appropriate protection in a well-ventilated area. It is flammable and should be stored away from oxidizers and heat. It tends to polymerize and may require inhibitors during storage.
