Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Dimethoxy-5-(methylsulfonyl)benzene.
1,3-Dimethoxy-5-(methylsulfonyl)benzene (CAS 38452-46-9), molecular formula C9H12O4S and molecular weight 216.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H12O4S, 1,3-Dimethoxy-5-(methylsulfonyl)benzene contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 216.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1,3-Dimethoxy-5-(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.
