5-Chloro-2-fluorobenzotrifluoride(CAS: 89634-74-2)

5-Chloro-2-fluorobenzotrifluoride is a white crystalline solid with a molecular weight of 261.02 g/mol. It has low solubility in water but is soluble in common organic solvents. It is highly reactive due to the presence of fluorine atoms. The compound is known for its high reactivity in nucleophilic substitution reactions.

5-Chloro-2-fluorobenzotrifluoride is typically synthesized through the reaction of 2-fluorobenzamide with thionyl chloride followed by trifluoromethylation. The reaction often requires a catalyst and proceeds with high selectivity, yielding pure product with a good yield.

5-Chloro-2-fluorobenzotrifluoride is used in the pharmaceutical industry for the synthesis of certain drugs, particularly those that require fluorine substitution. It is also utilized in the polymer industry for the production of fluorinated polymers and in the semiconductor industry for etching processes.

When handling 5-Chloro-2-fluorobenzotrifluoride, appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. Work should be conducted in a well-ventilated fume hood. Spills should be handled with caution using appropriate absorbents, and the material safety data sheet (MSDS) should be consulted for detailed spill procedures. Storage should be in a cool, dry place away from incompatible materials.
