Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its fluorinated structure enhances metabolic stability and bioavailability, making it valuable in creating selective serotonin reuptake inhibitors (SSRIs) and other neuroactive compounds. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the influence of the fluorine atom on binding affinity and pharmacokinetics. Also utilized in the preparation of enzyme inhibitors and receptor modulators where stereochemistry and polarity play critical roles in biological activity.
