2-(4-Fluorophenyl)-2-methylpropanoic acid(CAS: 93748-19-7)

2-(4-Fluorophenyl)-2-methylpropanoic acid is a white to off-white crystalline solid with a molecular weight of approximately 227.21 g/mol. It is slightly soluble in water but more soluble in organic solvents such as ethanol and acetone. Chemically, the compound is moderately reactive, especially with bases, and can undergo esterification and amide formation reactions.

2-(4-Fluorophenyl)-2-methylpropanoic acid is synthesized through a multistep process involving Friedel-Crafts alkylation and subsequent hydrolysis. Commonly, methylbenzene is treated with benzoyl chloride in the presence of aluminum chloride to form benzoylmethylbenzene. Further processing, including hydrogen fluoride mediation, yields the fluoro derivative, which is then hydrolyzed to obtain the desired acid.

2-(4-Fluorophenyl)-2-methylpropanoic acid is primarily used in the pharmaceutical industry as an intermediate in the synthesis of various medications. It also finds applications in the polymer industry for enhancing certain properties of polymers, and in sensor technology for specific chemical detection due to its fluorophore functionality.

When handling 2-(4-Fluorophenyl)-2-methylpropanoic acid, it is essential to wear adequate personal protective equipment (PPE) including safety goggles, gloves, and a lab coat. The compound should be used in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be handled with appropriate absorbents and disposed of according to local regulations. Always consult the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
