Used as a photolabile protecting group in organic synthesis, particularly in the controlled release of carboxylic acids and alcohols upon exposure to light. Its application is prominent in the preparation of light-sensitive prodrugs and in solid-phase peptide synthesis where selective deprotection is required without affecting other functional groups. Also utilized in the development of photoresponsive materials for drug delivery systems and lithographic technologies due to its clean photolysis and good stability under ambient conditions.
