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-((4-Chloro-3,5-dimethyl-1h-pyrazol-1-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 1006472-80-5), a certified reference material (molecular formula C9H12ClN5, MW 225.68 g/mol) for analytical method development and quality control.
The molecular framework of 1-((4-Chloro-3,5-dimethyl-1h-pyrazol-1-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine (C9H12ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
