Description
As a certified reference material (CRM), Dorzolamide Hydrochloride EP Impurity C 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 Dorzolamide Hydrochloride EP Impurity C (CAS CATO-C4X-122816), a pharmacopoeial impurity reference standard (molecular formula C10H17BN2O6S3HCl, MW 404.70 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Dorzolamide Hydrochloride EP Impurity C (C10H17BN2O6S3HCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 404.70 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
