Propyne, also known as methylacetylene, is an alkyne with the chemical formula C3H4. It is a colorless gas at room temperature and has a distinct, somewhat sweet odor. Propyne is characterized by its triple bond between the first and second carbon atoms, which imparts unique reactivity compared to alkenes and alkanes. It is flammable and can form explosive mixtures with air, necessitating careful handling and storage. Propyne is soluble in organic solvents but has limited solubility in water. It is primarily used in organic synthesis and as a fuel gas in welding and cutting applications. Additionally, propyne can undergo various reactions, including polymerization and addition reactions, making it a valuable intermediate in the production of other chemical compounds. Its CAS number, 74-99-7, is used for identification in chemical databases and regulatory contexts. Overall, propyne is an important compound in both industrial and laboratory settings due to its reactivity and utility in synthesis.
