Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where hydrazine derivatives serve as building blocks. Its structure allows for functionalization in heterocyclic ring formation, which is common in drugs targeting central nervous system disorders and antimicrobial agents. The presence of chlorine and fluorine enhances reactivity and binding affinity, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies. Also employed in research settings to prepare fluorinated analogs of biologically active molecules, aiding in the optimization of drug metabolism and pharmacokinetic properties.
