CH3CCCH2CH3

CH3CCCH2CH3, also known as 3-methylpent-1-yne or simply 3-methyl-1-pentyne, is a chemical compound with the molecular formula C6H10. It is an alkyne, characterized by the presence of a carbon-carbon triple bond. In this specific molecule, the triple bond is located at the terminal position of a five-carbon chain, with a methyl group attached to the third carbon atom.

This compound is a colorless liquid at room temperature and has a distinct odor. As an alkyne, it undergoes characteristic reactions, including addition reactions across the triple bond, such as hydrogenation, halogenation, and hydrohalogenation. The terminal alkyne functional group also allows for reactions like alkynylation and deprotonation by strong bases to form acetylides.

3-methylpent-1-yne can be synthesized through various organic chemistry routes. One common method involves the dehydrohalogenation of dihaloalkanes or the reaction of organometallic reagents with appropriate alkyl halides. Its applications are primarily found in organic synthesis, where it serves as a building block for more complex molecules. It can be used in the preparation of pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactive triple bond, it is a versatile intermediate in organic chemistry research and industrial processes.
