4-(Tert-butyl)phenylacetylene（Cat No.:L048583）is an organic compound featuring a phenyl ring substituted with a tert-butyl group at the para (4-) position and an ethynyl (acetylene) group at the 1-position. The tert-butyl group provides steric bulk and enhances lipophilicity, while the terminal alkyne serves as a reactive handle for cross-coupling reactions such as Sonogashira coupling or click chemistry. This compound is commonly used in the synthesis of advanced organic materials, including conjugated polymers, molecular electronics, and functional coatings. Its rigid structure and functional diversity make it valuable in materials science and medicinal chemistry.
