Chemical Structure

Valganciclovir Impurity 31 DiHCI CAS CATO-C4X-177431 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 757.20 g/mol gives Valganciclovir Impurity 31 DiHCI distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Valganciclovir Impurity 31 DiHCI (CAS CATO-C4X-177431, C29H44N12O10HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Valganciclovir Impurity 31 DiHCI (C29H44N12O10HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 757.20 g/mol, it falls into the 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), Valganciclovir Impurity 31 DiHCI 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.
