Chemical Structure
Description
As a certified reference material (CRM), Arbidol Sulfone 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.
CATO supplies Arbidol Sulfone (CAS 151455-32-2), a pharmacopoeial impurity reference standard (molecular formula C22H25BrN2O5S, MW 509.41 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Arbidol Sulfone (C22H25BrN2O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 509.41 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
