Description
CATO manufactures 比罗酯钠亚硝基杂质2 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.
比罗酯钠亚硝基杂质2 (CAS CATO-C3D-262838) is a certified pharmaceutical impurity reference standard with the molecular formula C26H25N9Na2O13S2 and a molecular weight of 781.64 g/mol.
Based on its molecular formula C26H25N9Na2O13S2, 比罗酯钠亚硝基杂质2 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 781.64 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.
