2-(4-Methoxyphenyl)sulfanylbenzoic acid (CAS 19862-91-0) is a high-purity analytical reference standard with the molecular formula C14H12O3S and a molecular weight of 260.31 g/mol.
2-(4-Methoxyphenyl)sulfanylbenzoic acid (C14H12O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
