Chemical Structure
Description
The occurrence of 1,4-Dimethyl-2-(methylsulfonyl)benzene 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.
CATO supplies 1,4-Dimethyl-2-(methylsulfonyl)benzene (CAS 6462-29-9), a certified reference material (molecular formula C9H12O2S, MW 184.26 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-Dimethyl-2-(methylsulfonyl)benzene (C9H12O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 1,4-Dimethyl-2-(methylsulfonyl)benzene 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.
