Used as a key intermediate in organic synthesis, particularly in the preparation of silicon-containing compounds for pharmaceuticals and agrochemicals. Its alkyne and hydroxyl functional groups allow for versatile reactivity, including coupling reactions and protection/deprotection strategies in multi-step syntheses. Commonly employed in the development of bioactive molecules where trimethylsilyl group acts as a protecting group or modulates lipophilicity. Also utilized in materials science for synthesizing specialty monomers and functionalized polymers.
