Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antihistamines and anti-inflammatory agents. Serves as a building block in organic synthesis for creating complex molecules with biological activity. Employed in the preparation of photoinitiators for polymer chemistry, where it helps initiate polymerization reactions under UV light. Also utilized in the study of coordination chemistry as a ligand for metal complexes, contributing to the design of catalysts and luminescent materials.
