Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of silyl-protected phenolic compounds. Its silyl group acts as a protecting group in organic synthesis, allowing selective reactions at other functional sites. Commonly employed in the preparation of liquid crystals and advanced materials due to its stability and reactivity in cross-coupling reactions. Also utilized in the development of silicon-based polymers and as a reagent in directed ortho-metalation reactions.
