1-Chloro-3,5-bis(trifluoromethyl)benzene(CAS: 328-72-3)

1-Chloro-3,5-bis(trifluoromethyl)benzene (CAS: 328-72-3) is a colorless or light yellow solid with a molecular weight of 299.62 g/mol. It has a low solubility in water but is freely soluble in organic solvents like dichloromethane and acetonitrile. The compound is known for its high reactivity towards nucleophiles and electrophiles. It is a potent electrophile due to the presence of the trifluoromethyl groups, which activate the benzene ring for substitution reactions.

1-Chloro-3,5-bis(trifluoromethyl)benzene (CAS: 328-72-3) can be synthesized via the Friedel-Crafts alkylation of 1-chlorobenzene (or benzene) with trifluoromethyl chloromethane in the presence of aluminum chloride as a catalyst. The reaction is typically carried out under anhydrous conditions to achieve high yield and selectivity. The product is usually purified by recrystallization or column chromatography.

1-Chloro-3,5-bis(trifluoromethyl)benzene (CAS: 328-72-3) is primarily used in the pharmaceutical and polymer industries. It serves as a precursor for the synthesis of various pharmaceutical intermediates and is also utilized in the preparation of fluorinated polymers. Its use in sensors and semiconductors is also reported due to its unique chemical and physical properties.

When handling 1-Chloro-3,5-bis(trifluoromethyl)benzene (CAS: 328-72-3), it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. The compound should be handled in a well-ventilated area or under a fume hood to avoid inhalation of 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 handling and safety information.
