Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N3-(sec-Butyl)-1-ethyl-1H-pyrazole-3,4-diamine dihydrochloride.
CATO supplies N3-(sec-Butyl)-1-ethyl-1H-pyrazole-3,4-diamine dihydrochloride (CAS 1431964-93-0), a certified reference material (molecular formula C9H18N4HCl, MW 218.73 g/mol) for analytical method development and quality control.
N3-(sec-Butyl)-1-ethyl-1H-pyrazole-3,4-diamine dihydrochloride (C9H18N4HCl) 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.
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.
