Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anticoagulant and antithrombotic agents. It serves as a building block for heterocyclic compounds due to its reactive carbonyl and ester functional groups, enabling ring transformations and condensation reactions. Commonly employed in medicinal chemistry for constructing quinoxaline-based scaffolds, which exhibit biological activities such as kinase inhibition and antimicrobial effects. Also utilized in agrochemical research for designing bioactive molecules with potential pesticidal or herbicidal properties.
