Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of heterocyclic systems important in medicinal chemistry. Commonly employed in the preparation of quinoxaline-based derivatives with potential antimicrobial, antiviral, and anticancer activities. Also utilized in research settings for designing fluorescent probes and sensors due to its electron-withdrawing nitro group and aldehyde functionality, enabling conjugation and signal detection in biochemical assays.
