Chemical Structure
Description
The occurrence of 2-(4-((2-Methoxy-5-(6-methyl-[1,2,4]triazolo[3,4-a]phthalazin-3-yl)phenyl)sulfonyl)piperazin-1-yl)ethanol is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-((2-Methoxy-5-(6-methyl-[1,2,4]triazolo[3,4-a]phthalazin-3-yl)phenyl)sulfonyl)piperazin-1-yl)ethanol (CAS 573935-11-2), molecular formula C23H26N6O4S and molecular weight 482.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-((2-Methoxy-5-(6-methyl-[1,2,4]triazolo[3,4-a]phthalazin-3-yl)phenyl)sulfonyl)piperazin-1-yl)ethanol (C23H26N6O4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
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 2-(4-((2-Methoxy-5-(6-methyl-[1,2,4]triazolo[3,4-a]phthalazin-3-yl)phenyl)sulfonyl)piperazin-1-yl)ethanol 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.
