Benzene,1-ethynyl-2-(methylthio)-

Description:

Benzene, 1-ethynyl-2-(methylthio)-, also known by its CAS number 78905-08-5, is an organic compound characterized by a benzene ring substituted with an ethynyl group and a methylthio group. The presence of the ethynyl group introduces a triple bond, which contributes to the compound's reactivity and potential applications in organic synthesis. The methylthio group, consisting of a sulfur atom bonded to a methyl group, can influence the compound's electronic properties and solubility. This compound is typically a colorless to pale yellow liquid with a distinctive aromatic odor. It is important in various chemical reactions, particularly in the synthesis of more complex organic molecules. Due to the presence of both the ethynyl and methylthio groups, it may exhibit unique chemical behavior, including potential participation in nucleophilic substitution and addition reactions. Safety precautions should be taken when handling this compound, as it may pose health risks, including toxicity and flammability.

Formula: C₉H₈S
