Chemical Structure

Ribavirin Impurity 48 CAS 613-83-2 chemical structure

Description

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.

CATO supplies Ribavirin Impurity 48 (CAS 613-83-2), a pharmacopoeial impurity reference standard (molecular formula C5H10O5, MW 150.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ribavirin Impurity 48 (C5H10O5) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 150.13 g/mol, it falls into the medium-molecular-weight range.

As a certified reference material (CRM), Ribavirin Impurity 48 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.
