2aminostyrene

2-Aminostyrene is an organic compound with the chemical formula C8H9N. It is a derivative of styrene where an amino group (-NH2) is attached to the ortho position of the phenyl ring. This compound is also known as ortho-aminostyrene or 2-vinyl aniline. It is a colorless liquid when pure, though it can darken upon exposure to air and light due to oxidation.

The synthesis of 2-aminostyrene can be achieved through various chemical routes, often involving the reduction of 2-nitrostyrene or the dehydration of 2-(1-hydroxyethyl)aniline. Due to the presence of both a vinyl group and an amino group, 2-aminostyrene exhibits reactivity characteristic of both functional groups. The amino group can undergo reactions typical of primary amines, such as acylation and alkylation, while the vinyl group can participate in polymerization reactions.

2-Aminostyrene can be used as a monomer in the synthesis of polymers, potentially leading to materials with specific optical or electronic properties. It can also serve as an intermediate in the production of pharmaceuticals, dyes, and other fine chemicals. Its handling requires caution due to its potential for polymerization and susceptibility to oxidation.
