4-Ethynyltoluene（Cat No.:L010792）is an aromatic compound consisting of a toluene (methylbenzene) core with an ethynyl group (–C≡CH) attached at the 4-position of the benzene ring. This structure provides both the hydrophobic character of the methyl group and the reactivity of the ethynyl group, making it useful in organic synthesis. The triple bond in the ethynyl group allows for further functionalization through reactions such as coupling, cross-coupling, or addition reactions. It is commonly employed in the synthesis of advanced materials, polymer chemistry, and as a building block for organic electronics or bioactive molecules.
