| Hazard Information | Back Directory | [Chemical Properties]
S-2-(4-chlorophenyl)-3-methylbutanoic acid is a white solid, mp106～107℃, insoluble in water, soluble in organic solvents such as toluene and benzene. | [Uses]
S-2-(4-chlorophenyl)-3-methylbutyric acid is an intermediate of S-fenvalerate (also known as S,S-fenvalerate, esfenvalerate), which can be used in related chemical in experimental research. | [Synthesis]
S-2-(4-chlorophenyl)-3-methylbutyric acid can be used with racemic 2-(4-chlorophenyl)-3-methylbutyric acid (referred to as butyric acid) with α-methylbenzylamine It can be obtained by splitting, but it is generally prepared by the dominant crystallization separation method in industry,. | [References]
