Photoremovable protecting group

{
  "id": "MLC-T-CHM-008921",
  "term": "Photoremovable protecting group",
  "field": "Chemistry",
  "definition": "A chemical moiety that reversibly blocks a reactive functional group in a molecule, preventing it from undergoing undesired reactions. This group can be selectively removed by irradiation with light of a specific wavelength, restoring the original reactivity of the functional group. Such groups are widely employed in organic synthesis, photolithography, and the controlled release of bioactive compounds.",
