Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-hydrazino-1-methyl-1H-pyrazole dihydrochloride (CAS 1955564-51-8) 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 5-hydrazino-1-methyl-1H-pyrazole 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.
CATO manufactures 5-hydrazino-1-methyl-1H-pyrazole 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.
