Chemical Structure
Description
The occurrence of 3-(Methylsulphonyl)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.
3-(Methylsulphonyl)benzoic Acid (CAS 5345-27-7) is a high-purity analytical reference standard with the molecular formula C8H8O4S and a molecular weight of 200.21 g/mol.
Based on its molecular formula C8H8O4S, 3-(Methylsulphonyl)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 200.21 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).
