Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3,5,6-Tetramethylbenzenesulfonyl chloride.
CATO supplies 2,3,5,6-Tetramethylbenzenesulfonyl chloride (CAS 60706-63-0), a certified reference material (molecular formula C10H13ClO2S, MW 232.73 g/mol) for analytical method development and quality control.
Structurally, 2,3,5,6-Tetramethylbenzenesulfonyl chloride (C10H13ClO2S) 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 232.73 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.
As a certified reference material (CRM), 2,3,5,6-Tetramethylbenzenesulfonyl chloride 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.
