Used primarily as a photoremovable protecting group in organic synthesis, especially for carboxylic acids and phosphate derivatives. Upon exposure to UV light, it undergoes efficient cleavage to release the protected molecule, making it valuable in controlled release applications such as drug delivery, biochemical assays, and phototriggered reactions in biological systems. Its high sensitivity to light and clean release profile allow for precise spatial and temporal control in research settings, particularly in studies requiring caged compounds.
