Description
CATO supplies Piretanide-d4 Methyl Ester (Major) (CAS 1794753-37-9), a certified reference material (molecular formula C18H16D4N2O5S, MW 380.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H16D4N2O5S, Piretanide-d4 Methyl Ester (Major) contains deuterium isotope labeling, a flavonoid core, 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 380.45 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Piretanide-d4 Methyl Ester (Major) 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.
