Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 462.93 g/mol gives Dorzagliatin Impurity N98 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dorzagliatin Impurity N98 (CAS 1191996-10-7), a pharmacopoeial impurity reference standard (molecular formula C22H27ClN4O5, MW 462.93 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Dorzagliatin Impurity N98 (C22H27ClN4O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 462.93 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.
As a certified reference material (CRM), Dorzagliatin Impurity N98 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.
