Used in the synthesis of pharmaceuticals, particularly in the production of antitubercular and antiviral drugs. Acts as a building block in the development of active pharmaceutical ingredients due to its ability to form complex heterocyclic structures. Employed in agrochemicals for the formulation of certain pesticides and herbicides. Serves as a ligand in coordination chemistry for catalysts used in organic transformations. Applied in research laboratories as a reagent for derivatization in analytical methods. Also utilized in the preparation of dyes and photochemical sensors due to its fluorescent properties when derivatized.
