Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 266.21 g/mol gives Tenofovir Impurity 38 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tenofovir Impurity 38 (CAS 161760-09-4), a pharmacopoeial impurity reference standard (molecular formula C8H11O6PS, MW 266.21 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C8H11O6PS, Tenofovir Impurity 38 contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Impurity 38 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.
