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.
CATO supplies 1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)-1H-imidazole-4-carboxylic acid (CAS 1708268-79-4), a certified reference material (molecular formula C10H9ClN4O3, MW 268.66 g/mol) for analytical method development and quality control.
The molecular framework of 1-(5-Chloro-1-ethyl-6-oxo-1,6-dihydropyridazin-4-yl)-1H-imidazole-4-carboxylic acid (C10H9ClN4O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
