4-Methyl-3-(propane-2-sulfonyl)benzoic acid CAS 1152497-12-5

Description

The occurrence of 4-Methyl-3-(propane-2-sulfonyl)benzoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methyl-3-(propane-2-sulfonyl)benzoic acid (CAS 1152497-12-5), molecular formula C11H14O4S and molecular weight 242.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H14O4S, 4-Methyl-3-(propane-2-sulfonyl)benzoic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
