Used as an intermediate in the synthesis of agricultural chemicals, particularly herbicides and fungicides. It plays a key role in developing active ingredients that improve crop protection by enhancing selectivity and efficacy. Also utilized in the production of dyes and fluorescent whiteners due to its stable heterocyclic structure. Its derivatives are explored in pharmaceutical research for potential bioactive properties, including antimicrobial and anti-inflammatory applications. Commonly employed in organic synthesis where the chloro and ethoxy groups allow for further functionalization.
