Tolvaptan Impurity 83 CAS 942619-79-6

Description

Compared with other compounds in its class, the molecular weight of 549.90 g/mol gives Tolvaptan Impurity 83 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Tolvaptan Impurity 83 (CAS 942619-79-6, C26H24ClN2O6PNa) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a salt form, a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, Tolvaptan Impurity 83 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 549.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Tolvaptan Impurity 83 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.
