Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to undergo selective functionalization on the aromatic ring and lactam nitrogen. Commonly employed in research settings to design bioactive molecules targeting neurological disorders and inflammatory diseases. Also utilized in the preparation of fluorescent probes for biochemical assays owing to its nitro group’s electron-withdrawing properties and inherent ring structure favorable for conjugation.
