CATO supplies S,S'-(ethane-1,2-diyl) bis(4-methylbenzenesulfonothioate) (CAS 2225-23-2), a certified reference material (molecular formula C16H18O4S4, MW 402.57 g/mol) for analytical method development and quality control.
Structurally, S,S'-(ethane-1,2-diyl) bis(4-methylbenzenesulfonothioate) (C16H18O4S4) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 402.57 g/mol, it falls into the moderately-high-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).
As a certified reference material (CRM), S,S'-(ethane-1,2-diyl) bis(4-methylbenzenesulfonothioate) 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.
