4-Methylsulphonylphenylacetic acid (4-MSP) (CAS NO : 90536-66-6)

4-Methylsulphonylphenylacetic acid (CAS No: 90536-66-6) serves as a vital aromatic building block in the pharmaceutical sector, primarily functioning as a critical intermediate in the synthesis of selective COX-2 inhibitors such as Etoricoxib and various heterocyclic diaryl compounds. This organic derivative is increasingly integrated into the development of novel anti-inflammatory and analgesic agents due to its methylsulfonyl-substituted phenylacetic acid structure, which facilitates precise interactions with biological targets. Beyond medicinal chemistry, the compound is gaining traction as a versatile raw material in the agrochemical and dyestuff industries, where its stability and solubility in polar solvents support complex organic synthesis and the creation of high-performance specialty chemicals.
