As a certified reference material (CRM), Tenofovir disoproxil Impurity 80 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.
CATO supplies Tenofovir disoproxil Impurity 80 (CAS CATO-C4X-107680), a pharmacopoeial impurity reference standard (molecular formula C13H22N5O4PC4H4O4, MW 459.40 g/mol) used for the identification and quantification of trace impurities in APIs.
Tenofovir disoproxil Impurity 80 (C13H22N5O4PC4H4O4) contains a flavonoid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
