Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 184.26 g/mol gives 1-Methyl-2-((methylsulfonyl)methyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Methyl-2-((methylsulfonyl)methyl)benzene (CAS 261924-13-4), molecular formula C9H12O2S and molecular weight 184.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Methyl-2-((methylsulfonyl)methyl)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-Methyl-2-((methylsulfonyl)methyl)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.
