Used as a photoinitiator in UV-curable systems, enabling rapid polymerization in coatings, inks, and adhesives upon exposure to ultraviolet light. Also investigated for its potential biological activity, including antimicrobial, antioxidant, and anti-inflammatory properties (such as enzyme inhibition related to inflammation), making it relevant in pharmaceutical and agrochemical research. Additionally serves as a building block in organic synthesis for developing more complex xanthone derivatives with tailored functional properties, and as a reference standard in laboratory analysis of plant extracts to identify structurally similar compounds.
