CH3CHCH3CH2NH2

CH3CHCH3CH2NH2 is an aliphatic primary amine commonly known as isobutylamine. Its IUPAC name is 2-methylpropan-1-amine, and its molecular formula is C4H11N. In SMILES notation it is CC(C)CN, reflecting a branched butyl chain connected to a terminal amine group. The compound belongs to the class of alkylamines and is structurally related to n-butylamine but with a methyl substituent on the second carbon.

Isobutylamine is a colorless, volatile liquid with an amine odor typical of low-molecular-weight amines. It is miscible with water and many organic solvents due to its polar amino group, which can engage in hydrogen bonding. As a primary amine, it acts as a weak base, readily forming salts with acids.

Applications and synthesis options are oriented toward chemical synthesis and industry. Isobutylamine serves as an intermediate in the production of pharmaceuticals, agrochemicals, dyes, and other organic compounds. It can be introduced into reaction sequences via standard amination and condensation strategies and is often handled as a reactive building block in manufacturing settings.

Safety and handling: as with most volatile amines, isobutylamine can be irritating to skin, eyes, and the respiratory tract. It is flammable and should be stored and used in appropriate containment with good ventilation. Proper protection includes gloves and eye protection, and it should be handled away from oxidizers. It forms ammonium salts upon reaction with acids, and these salts are often used to facilitate handling and purification.
