Chemical Structure

3-Methyl-1H-pyrazole-4,5-diamine dihydrochloride CAS 199340-92-6 chemical structure

Description

CATO manufactures 3-Methyl-1H-pyrazole-4,5-diamine dihydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

3-Methyl-1H-pyrazole-4,5-diamine dihydrochloride (CAS 199340-92-6) is a high-purity analytical reference standard with the molecular formula C4H8N4HCl and a molecular weight of 148.59 g/mol.

The molecular framework of 3-Methyl-1H-pyrazole-4,5-diamine dihydrochloride (C4H8N4HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
