Chemical Structure
Description
CATO supplies 1-Methyl-1h-pyrazole-4-carboximidamide hydrochloride (CAS 1267500-60-6), a certified reference material (molecular formula C5H8N4HCl, MW 160.60 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 1-Methyl-1h-pyrazole-4-carboximidamide hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
