Chemical Structure
Description
The molecular framework of 62437-99-4 2-Pyridone hydrazone dihydrochloride EINECS 263-541-3 2-Pyridone hydrazone HCl (C5H13N3HCl) is characterized by 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.
CATO supplies 62437-99-4 2-Pyridone hydrazone dihydrochloride EINECS 263-541-3 2-Pyridone hydrazone HCl (CAS 62437-99-4), a certified reference material (molecular formula C5H13N3HCl, MW 151.64 g/mol) for analytical method development and quality control.
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.
