3-Ethynylaniline（Cat No.:R057425）is an aromatic amine compound with the molecular formula C8H7N, featuring an ethynyl group (-C≡CH) at the meta (3-) position relative to the amino group on a benzene ring. It is a light yellow to brown liquid or solid, depending on conditions, and serves as a versatile intermediate in organic synthesis. The presence of both the ethynyl and amino functionalities allows for diverse chemical transformations, including Sonogashira couplings and formation of heterocycles. 3-Ethynylaniline is commonly used in the synthesis of dyes, pharmaceuticals, agrochemicals, and advanced materials such as organic semiconductors.
