Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 447.38 g/mol gives Tenofovir disoproxil Impurity 113 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tenofovir disoproxil Impurity 113 (CAS CATO-C4X-1076113), a pharmacopoeial impurity reference standard (molecular formula C16H26N5O8P, MW 447.38 g/mol) used for the identification and quantification of trace impurities in APIs.
Tenofovir disoproxil Impurity 113 (C16H26N5O8P) 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).
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.
As a certified reference material (CRM), Tenofovir disoproxil Impurity 113 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.
