Chemical Structure

1,4-dimethyl-1H-pyrazol-5-amine hydrochloride CAS 76606-33-2 chemical structure

Description

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.

CATO supplies 1,4-dimethyl-1H-pyrazol-5-amine hydrochloride (CAS 76606-33-2), a certified reference material (molecular formula C5H9N3HCl, MW 147.61 g/mol) for analytical method development and quality control.

The molecular framework of 1,4-dimethyl-1H-pyrazol-5-amine hydrochloride (C5H9N3HCl) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
