Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Bromo-1H-pyrazol-1-yl)acetimidamide (hydrochloride).
CATO supplies 2-(4-Bromo-1H-pyrazol-1-yl)acetimidamide (hydrochloride) (CAS 2225142-39-0), a certified reference material (molecular formula C5H7BrN4HCl, MW 239.50 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Bromo-1H-pyrazol-1-yl)acetimidamide (hydrochloride) (C5H7BrN4HCl) is characterized by a nitrile group, chlorine/bromine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
