Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 202.29 g/mol gives 1-Methyl-4-[(methylsulfanyl)sulfonyl]benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Methyl-4-[(methylsulfanyl)sulfonyl]benzene (CAS 4973-66-4), molecular formula C8H10O2S2 and molecular weight 202.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-Methyl-4-[(methylsulfanyl)sulfonyl]benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
