Used as a photolabile protecting group in organic synthesis, particularly in the controlled release of carboxylic acids, amines, and alcohols upon exposure to UV light. Its application is valuable in solid-phase synthesis, peptide chemistry, and the development of light-responsive materials. Due to its efficient cleavage under mild conditions, it is employed in the synthesis of sensitive biomolecules and in drug delivery systems where spatial and temporal control is required. Also utilized in the fabrication of microarrays and in studies involving caged compounds for biological signaling.
