1-Ethyl-2-ethynylbenzene, also known by its CAS number 75659-49-3, is an organic compound characterized by its aromatic structure, which includes a benzene ring substituted with both an ethyl group and an ethynyl group. This compound typically exhibits a colorless to pale yellow liquid form and has a distinct aromatic odor. It is insoluble in water but soluble in organic solvents, reflecting its hydrophobic nature. The presence of the ethynyl group introduces a triple bond, contributing to its reactivity and potential for undergoing various chemical reactions, such as polymerization or addition reactions. The compound's boiling point and melting point are influenced by its molecular structure and substituents, which also affect its physical properties. 1-Ethyl-2-ethynylbenzene is utilized in organic synthesis and may serve as an intermediate in the production of more complex chemical entities. Safety precautions should be observed when handling this compound, as it may pose health risks if inhaled or ingested.
