Used primarily as a photoremovable protecting group in organic synthesis, especially for carboxylic acids and phosphates. Upon exposure to UV or visible light, it undergoes clean photolysis, releasing the protected molecule. This makes it valuable in controlled release applications, such as in drug delivery systems and biochemical studies where precise temporal and spatial control of molecule activation is required. Its difluoro substitution enhances photoreactivity and stability in biological environments, making it suitable for use in aqueous media and cellular assays.
