6-Bromo-5-fluoro-3-pyridinamine(CAS: 1256276-41-1)

6-Bromo-5-fluoro-3-pyridinamine is a crystalline solid with a molecular weight of approximately 229.03 g/mol. It has limited water solubility and is slightly soluble in common organic solvents like ethanol and acetone. The compound exhibits moderate reactivity, particularly towards nucleophiles, making it suitable for various chemical transformations. It is stable under normal laboratory conditions but should be stored in a dry environment to prevent hydrolysis.

6-Bromo-5-fluoro-3-pyridinamine is typically synthesized via the bromination of 5-fluoro-3-pyridinamine followed by amination. Common methods include the use of N-bromosuccinimide (NBS) in the presence of a radical initiator, followed by treatment with an appropriate amine. The reaction is performed in an inert solvent such as dichloromethane or acetonitrile, with a yield of approximately 70-80%. The selectivity and purity can be enhanced through the use of chiral auxiliaries and phase transfer catalysts.

6-Bromo-5-fluoro-3-pyridinamine finds applications in the pharmaceutical industry for the synthesis of biologically active compounds. It is also utilized in the development of sensors and as a functional group in the preparation of advanced materials.
