Chemical Structure
Description
CATO supplies Tenofovir disoproxil Impurity 133 (CAS CATO-C4X-1076133), a pharmacopoeial impurity reference standard (molecular formula C34H51N11O18P2, MW 963.78 g/mol) used for the identification and quantification of trace impurities in APIs.
Tenofovir disoproxil Impurity 133 (C34H51N11O18P2) 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 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.
CATO manufactures Tenofovir disoproxil Impurity 133 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
