Chemical Structure
Description
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.
N1-(3-Ethoxypropyl)-N2-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)oxalamide (CAS 946219-95-0) is a high-purity analytical reference standard with the molecular formula C16H20N4O4 and a molecular weight of 332.35 g/mol.
The molecular framework of N1-(3-Ethoxypropyl)-N2-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)oxalamide (C16H20N4O4) is characterized by a flavonoid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures N1-(3-Ethoxypropyl)-N2-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)oxalamide 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.
