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 4-amino-N,N,1-trimethyl-1H-pyrazole-3-carboxamide hydrochloride (CAS 1803598-20-0), a certified reference material (molecular formula C7H12N4OHCl, MW 204.66 g/mol) for analytical method development and quality control.
The molecular framework of 4-amino-N,N,1-trimethyl-1H-pyrazole-3-carboxamide hydrochloride (C7H12N4OHCl) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
