Used primarily as an intermediate in the synthesis of pharmaceutical compounds, especially in the development of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant drugs. Its structure supports the formation of active metabolites that influence central nervous system activity. It also serves in research settings for designing novel bioactive molecules due to its electron-donating and hydrogen-bonding capabilities. Additionally, it is employed in the preparation of dyes and fluorescent probes for biochemical labeling, benefiting from its nitro and amino functional groups that enhance optical properties.
