Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of trifluoromethyl-substituted heterocyclic drugs. Its hydrazine functionality enables cyclization reactions to form pyrazole, triazole, or indole derivatives, which are common scaffolds in medicinal chemistry. The presence of both bromo and trifluoromethyl groups allows for further functionalization via cross-coupling reactions, making it valuable in structure-activity relationship (SAR) studies. Commonly employed in research settings for designing bioactive molecules with potential antitumor, anti-inflammatory, or antimicrobial properties.
