4aminostyrene

4aminostyrene, also known as p-aminostyrene or 4-vinylaniline, is an organic compound with the chemical formula C8H9N. It is a derivative of styrene, where an amino group (-NH2) is attached to the para position of the phenyl ring. At room temperature, 4aminostyrene typically exists as a liquid or a low-melting solid. It is characterized by its aromatic ring and a vinyl group, which is responsible for its ability to undergo polymerization.

The presence of the amino group makes 4aminostyrene a weakly basic compound. It can react with acids to form salts. The amino group also influences the reactivity of the vinyl group, making it susceptible to various chemical transformations, including addition reactions and polymerization. 4aminostyrene can be polymerized to form poly(4aminostyrene), a polymer with potential applications in materials science and as an intermediate in the synthesis of other complex molecules.

4aminostyrene is synthesized through various chemical routes, often involving the reduction of nitrostyrene derivatives or the amination of styrene precursors. Its applications are primarily found in research and development, serving as a monomer for specialized polymers and as a building block in organic synthesis. Due to its reactive nature, proper handling and storage procedures are necessary to prevent unintended polymerization or degradation. It is typically handled with care in laboratory settings.
