Description
CATO supplies Telmisartan Impurity N20 (CAS 1083158-65-9), a pharmacopoeial impurity reference standard (molecular formula C19H22N4O, MW 322.40 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C19H22N4O, Telmisartan Impurity N20 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.40 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.
CATO manufactures Telmisartan Impurity N20 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.
