3-((2-(tert-butoxycarbonyl)-5,7-dichloro-1,2,3,4-tetrahydroisoquinoline-6-carbonyl)oxy)-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide (CAS CATO-C3D-5794), molecular formula C20H19Cl2N5O5 and molecular weight 480.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((2-(tert-butoxycarbonyl)-5,7-dichloro-1,2,3,4-tetrahydroisoquinoline-6-carbonyl)oxy)-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide (C20H19Cl2N5O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO manufactures 3-((2-(tert-butoxycarbonyl)-5,7-dichloro-1,2,3,4-tetrahydroisoquinoline-6-carbonyl)oxy)-3H-[1,2,3]triazolo[4,5-b]pyridine 1-oxide 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.
