Description
As a certified reference material (CRM), 5-Hydrazineyl-1,4-dimethyl-1H-pyrazole dihydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
5-Hydrazineyl-1,4-dimethyl-1H-pyrazole dihydrochloride (CAS 1855891-42-7), molecular formula C5H10N4HCl and molecular weight 162.62 g/mol, is a CATO reference standard with documented purity and traceability.
5-Hydrazineyl-1,4-dimethyl-1H-pyrazole dihydrochloride (C5H10N4HCl) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
