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 5-Hydrazineyl-1,3-dimethyl-1H-pyrazole dihydrochloride (CAS 1855891-19-8), a certified reference material (molecular formula C5H10N4HCl, MW 162.62 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H10N4HCl, 5-Hydrazineyl-1,3-dimethyl-1H-pyrazole dihydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 162.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
