3aminopropene

3-Aminopropene, also known as allylamine, is an organic compound with the chemical formula C3H7N. It is a colorless liquid with a characteristic ammoniacal odor. 3-Aminopropene is a primary amine and an alkene, possessing both an amino group and a double bond. This dual functionality makes it a reactive molecule used in various chemical synthesis processes.

The synthesis of 3-aminopropene typically involves the reaction of allyl chloride with ammonia. It can also be produced through the reduction of acrylonitrile or the amination of allyl alcohol. Its physical properties include a boiling point of around 55-57 °C and a density slightly less than water. 3-Aminopropene is miscible with water and many organic solvents.

Due to the presence of the amino group, 3-aminopropene acts as a nucleophile and a base. The double bond allows for addition reactions, such as polymerization and halogenation. Its primary applications are as a monomer in the production of polymers, particularly poly(allylamine), which is used in water treatment, flocculation, and as a component in coatings and adhesives. It also serves as an intermediate in the synthesis of pharmaceuticals and other fine chemicals. For instance, it is a precursor to antifungal drugs like terbinafine. Handling of 3-aminopropene requires caution as it is flammable and can cause skin and eye irritation.
