4-oxo-1,4-dihydropyridazine-3-carboxylic acid CAS 17417-55-9

Description

The occurrence of 4-oxo-1,4-dihydropyridazine-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-oxo-1,4-dihydropyridazine-3-carboxylic acid (CAS 17417-55-9), a certified reference material (molecular formula C5H8N2O3, MW 144.13 g/mol) for analytical method development and quality control.

The molecular framework of 4-oxo-1,4-dihydropyridazine-3-carboxylic acid (C5H8N2O3) is characterized by an amino-acid-derived structure, 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. 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 4-oxo-1,4-dihydropyridazine-3-carboxylic acid 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.
