4-(Trifluoromethyl)benzyl chloride(CAS: 939-99-1)

4-(Trifluoromethyl)benzyl chloride (CAS: 939-99-1) is a colorless liquid with a molecular weight of 252.03 g/mol. It has a low melting point of -20°C and a boiling point of 120°C. It is highly soluble in organic solvents like chloroform and acetone but insoluble in water. It reacts with bases to form trifluoromethylated amines and is highly reactive due to the presence of the trifluoromethyl group.

4-(Trifluoromethyl)benzyl chloride is typically synthesized via a reaction between 4-(trifluoromethyl)benzyl alcohol and thionyl chloride in the presence of a suitable base. The reaction proceeds via an esterification followed by acid chloride formation. The yield is typically around 85%, with high selectivity for the desired product.

4-(Trifluoromethyl)benzyl chloride (CAS: 939-99-1) is used in the pharmaceutical industry for the synthesis of complex organic molecules, in polymer synthesis for its ability to introduce fluorine-containing groups, in sensor technology for its reactivity, and in semiconductor manufacturing for its use in various etching processes.

When handling 4-(Trifluoromethyl)benzyl chloride, it is essential to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood to minimize exposure. Spills should be carefully cleaned up with appropriate absorbent materials, and the area should be well-ventilated. Always refer to the Safety Data Sheet (SDS) for specific handling instructions and first aid measures.
