Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) targeting central nervous system disorders. It serves as a building block in medicinal chemistry due to its ability to act as a linker or functional group modifier, enhancing solubility and bioavailability of drug candidates. Commonly employed in the preparation of kinase inhibitors and receptor antagonists. Also utilized in research settings for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
