Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.65 g/mol gives Methyl 4-chlorobenzenesulfinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 4-chlorobenzenesulfinate (CAS 26760-21-4), a certified reference material (molecular formula C7H7ClO2S, MW 190.65 g/mol) for analytical method development and quality control.
Structurally, Methyl 4-chlorobenzenesulfinate (C7H7ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 190.65 g/mol, it falls into the medium-molecular-weight range. 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.
