Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It is also employed in the creation of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its fluorinated heterocyclic structure enhances binding affinity and metabolic stability in drug candidates. Commonly found in research related to antiviral and anti-inflammatory agents due to its favorable electronic and steric properties.
