Used in organic synthesis as a protecting group for alcohols, particularly in complex molecule construction. It facilitates selective reactions by temporarily masking hydroxyl groups, ensuring desired transformations occur without interference. Commonly employed in peptide and carbohydrate chemistry, where precise control over reactivity is crucial. Also serves as an intermediate in the preparation of pharmaceuticals and fine chemicals, enabling the introduction of specific functional groups. Its stability under various reaction conditions makes it a versatile tool in multi-step synthetic processes.
