Description
As a certified reference material (CRM), Tenofovir disoproxil Impurity 141 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.
Tenofovir disoproxil Impurity 141 (CAS CATO-C4X-1076141) is a certified pharmaceutical impurity reference standard with the molecular formula C22H30N5O5P and a molecular weight of 475.48 g/mol.
Based on its molecular formula C22H30N5O5P, Tenofovir disoproxil Impurity 141 contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 475.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
