1-(Dichloromethyl)-2-(trifluoromethyl)benzene(CAS: 707-72-2)

1-(Dichloromethyl)-2-(trifluoromethyl)benzene is a crystalline solid with a molecular weight of approximately 267.88 g/mol. It is slightly soluble in common organic solvents and has low reactivity under normal conditions. However, it is highly reactive towards nucleophiles due to the presence of the dichloromethyl and trifluoromethyl groups.

1-(Dichloromethyl)-2-(trifluoromethyl)benzene is typically synthesized via a nucleophilic substitution reaction of 2-(trifluoromethyl)benzoyl chloride with methyl chlorosilane. The reaction is carried out in the presence of a Lewis acid catalyst like aluminum chloride to enhance the reactivity and yield of the product.

1-(Dichloromethyl)-2-(trifluoromethyl)benzene is primarily used in the pharmaceutical industry for the synthesis of active pharmaceutical ingredients. It is also utilized in the polymer industry for the modification of polymer properties and in semiconductor manufacturing for its use as a photoresist material.

When handling 1-(Dichloromethyl)-2-(trifluoromethyl)benzene, it is crucial to use appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat. Ensure to work in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up immediately using appropriate safety protocols and materials as outlined in the Material Safety Data Sheet (MSDS).
