Propargyl alcohol is a colorless, viscous liquid with a slightly pungent odor. It has a boiling point of 113 degrees Celsius and a melting point of -14 degrees Celsius, making it a stable liquid at room temperature. One of its most notable features is the presence of both an alcohol functional group (-OH) and a terminal alkyne group (C≡C), which imparts unique reactivity compared to other alcohols.
