3,4-Dimethoxyphenylmethylsulfoxide CAS 38417-24-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,4-Dimethoxyphenylmethylsulfoxide (CAS 38417-24-2) is a high-purity analytical reference standard with the molecular formula C9H12O3S and a molecular weight of 200.25 g/mol.

3,4-Dimethoxyphenylmethylsulfoxide (C9H12O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

As a certified reference material (CRM), 3,4-Dimethoxyphenylmethylsulfoxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
