Used as a protected intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. The silyl ether group provides stability to the hydroxyl functionality while allowing selective deprotection under mild conditions, making it valuable in multi-step synthesis. Commonly employed in the development of kinase inhibitors and other medicinal agents where azetidine serves as a rigid scaffold. Its protected form enhances solubility and compatibility with various reaction conditions, including cross-coupling and nucleophilic substitution reactions.
