Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of neuroactive compounds and central nervous system agents. It serves as a building block in the preparation of selective enzyme inhibitors and receptor modulators due to the presence of the fluorobenzyl group, which enhances metabolic stability and bioavailability. Commonly employed in the manufacture of antidepressants, antipsychotics, and investigational drugs targeting neurological disorders. Its hydrazine functionality allows for facile derivatization into heterocyclic structures such as indoles, pyrazoles, and triazoles, which are prevalent in medicinal chemistry. Also utilized in research settings for labeling and probe development owing to the fluorine atom’s utility in 19F NMR studies.
