Used primarily as a photoremovable protecting group in organic synthesis, especially in the controlled release of carboxylic acids, phosphates, and other functional groups upon exposure to light. Its application is valuable in biological research for triggering molecular activity with light, enabling precise spatial and temporal control in living systems. Commonly employed in the design of light-activated drugs, sensors, and caged compounds for studying fast biochemical processes. Also utilized in photochemical studies due to its efficient cleavage under UV or visible light, making it suitable for labile substrate delivery in chemical and biochemical assays.
