2-Bromo-3-chloro-5-fluoropyridine(CAS: 1214326-94-9)

2-Bromo-3-chloro-5-fluoropyridine is a crystalline solid with a molecular weight of approximately 228.03 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is moderately reactive, particularly in the presence of strong bases or reducing agents. It can undergo substitution reactions and is often used as a precursor in organic synthesis.

2-Bromo-3-chloro-5-fluoropyridine is typically synthesized through electrophilic aromatic substitution reactions. A common method involves the substitution of a pyridine ring with bromine followed by the introduction of a chlorine atom and a fluorine atom. Catalysts such as fuming sulfuric acid or Lewis acids are often used to enhance the reactivity and selectivity of the reactions.

2-Bromo-3-chloro-5-fluoropyridine is primarily used in the pharmaceutical industry for the synthesis of various drug candidates. It also finds applications in the polymer industry for the development of new materials with specific properties. Additionally, it is used in sensor technology and semiconductor manufacturing, although to a lesser extent compared to its pharmaceutical applications.

When handling 2-Bromo-3-chloro-5-fluoropyridine, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize exposure to harmful vapors. Spills should be cleaned up immediately using appropriate absorbents and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
