Used primarily in pharmaceutical research and development as a key intermediate in the synthesis of various active pharmaceutical ingredients (APIs). It plays a crucial role in the preparation of compounds with potential therapeutic applications, particularly in the fields of oncology and infectious diseases. Its structural features make it valuable for modifying and optimizing drug molecules to enhance efficacy and selectivity. Additionally, it is utilized in organic synthesis for constructing complex heterocyclic frameworks, which are essential in medicinal chemistry. Its halogenated nature also allows for further functionalization, enabling the creation of diverse chemical libraries for drug discovery.
