Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive compounds and drug candidates targeting inflammation and central nervous system disorders. Its aldehyde functional group allows for easy modification, enabling the formation of imines, oximes, and other derivatives useful in medicinal chemistry. Also employed in the preparation of fluorescent dyes and optical brighteners due to its favorable electronic properties. Commonly found in agrochemical research for designing new pesticides and herbicides with improved efficacy. Its heterocyclic core contributes to enhanced metabolic stability in final active ingredients.
