Used as a key intermediate in organic synthesis, particularly in the pharmaceutical and agrochemical industries. Its alkyne functionality combined with the trimethylsilyl group allows for selective reactions, such as Sonogashira couplings and deprotection to form terminal alkynes. It is also employed in the preparation of functionalized polymers and specialty materials where controlled molecular architecture is required. The hydroxyl group enables further derivatization, making it useful in building complex molecules through multi-step synthesis.
