4-Methyl-4'-pentylbiphenyl(CAS: 64835-63-8)

4-Methyl-4'-pentylbiphenyl is a clear, colorless liquid with a molecular weight of approximately 224.34 g/mol. It has a melting point of -43.7°C, a boiling point of 222-225°C, and a solubility in water of less than 0.1 g/L. It is moderately reactive and may undergo substitution reactions under certain conditions.

4-Methyl-4'-pentylbiphenyl is typically synthesized via a Friedel-Crafts alkylation reaction where a methyl group is introduced to the ortho position of a biphenyl derivative followed by alkylation using pentyl bromide. The reaction is catalyzed by aluminum chloride and proceeds with high selectivity and yield.

4-Methyl-4'-pentylbiphenyl is used in various industries, including pharmaceuticals for drug intermediates, in the polymer industry for speciality plastics and coatings, and in the sensor industry for its use in gas sensing applications. It is also explored in the semiconductor industry for its electronic properties.

Proper personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat should be worn when handling 4-Methyl-4'-pentylbiphenyl. It should be stored in a cool, well-ventilated area away from heat sources and incompatible materials. In case of spill, use appropriate spill response materials and refer to the Safety Data Sheet (SDS) for detailed instructions.
