Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 183.56 g/mol gives N-Nitroso Tenofovir Impurity 68 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, N-Nitroso Tenofovir Impurity 68 (CAS CATO-C4X-179768, C5H2ClN5O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-Nitroso Tenofovir Impurity 68 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), N-Nitroso Tenofovir Impurity 68 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.
