Chemical Structure

1H-pyrazole-4,5-diamine,2HCl CAS 131311-65-4 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.

1H-pyrazole-4,5-diamine,2HCl (CAS 131311-65-4) is a high-purity analytical reference standard with the molecular formula C3H6N4HCl and a molecular weight of 134.57 g/mol.

The molecular framework of 1H-pyrazole-4,5-diamine,2HCl (C3H6N4HCl) 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.

CATO manufactures 1H-pyrazole-4,5-diamine,2HCl 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.
