Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1171579-22-8 2-{[1-(5-Chloro-2-methylphenyl)-6-oxo-1,2,3,6-tetrahydropyridazin-3-yl]oxy}butanoic acid MFCD14281704.
1171579-22-8 2-{[1-(5-Chloro-2-methylphenyl)-6-oxo-1,2,3,6-tetrahydropyridazin-3-yl]oxy}butanoic acid MFCD14281704 (CAS 1171579-22-8) is a high-purity analytical reference standard with the molecular formula C15H17ClN2O4 and a molecular weight of 324.76 g/mol.
The molecular framework of 1171579-22-8 2-{[1-(5-Chloro-2-methylphenyl)-6-oxo-1,2,3,6-tetrahydropyridazin-3-yl]oxy}butanoic acid MFCD14281704 (C15H17ClN2O4) 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).
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.
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.
