Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and anti-inflammatory drugs. Its structure allows for selective substitution at multiple sites, making it valuable in medicinal chemistry for constructing bioactive molecules. Commonly employed in the preparation of benzoxazine derivatives that exhibit potential as kinase inhibitors or antimicrobial agents. Also utilized in research settings to explore new pathways in heterocyclic chemistry due to its reactivity and stability under various coupling conditions.
