1-Fluoro-4-nitro-2-(trifluoromethyl)benzene(CAS: 400-74-8)

1-Fluoro-4-nitro-2-(trifluoromethyl)benzene is a crystalline solid with a molecular weight of approximately 261.04 g/mol. It has a melting point of 108-109°C and is only slightly soluble in water but soluble in common organic solvents like ethanol and acetone. The compound is highly reactive due to the presence of the nitro and trifluoromethyl groups, which make it a strong electrophile in chemical reactions.

1-Fluoro-4-nitro-2-(trifluoromethyl)benzene is typically synthesized by the nitration of 1-fluoro-2-(trifluoromethyl)benzene using a mixture of nitric and sulfuric acids. The reaction is carried out in a solvent like acetic acid at a temperature around 50°C. The product is then purified by recrystallization from a suitable solvent to obtain the crystalline form.

1-Fluoro-4-nitro-2-(trifluoromethyl)benzene is used in the pharmaceutical industry for the synthesis of certain drugs. It is also utilized in the polymer industry for the production of special polymers with enhanced properties. Additionally, it finds applications in the semiconductor industry as a precursor for the production of electronic materials and in the chemical sensors industry for developing gas-sensing devices.

When handling 1-Fluoro-4-nitro-2-(trifluoromethyl)benzene, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. This compound should be handled in a well-ventilated area or a fume hood to avoid inhaling the vapors. Spills should be cleaned up using appropriate absorbent materials and disposed of according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed handling and storage information.
