Tenofovir disoproxil Impurity 131 CAS CATO-C4X-1076131

Description

The occurrence of Tenofovir disoproxil Impurity 131 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Tenofovir disoproxil Impurity 131 (CAS CATO-C4X-1076131, C29H42N12O16P2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Tenofovir disoproxil Impurity 131 (C29H42N12O16P2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Tenofovir disoproxil Impurity 131 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.
