Description
CATO supplies 4-Bromo-1-pyrrolidin-3-yl-1H-pyrazole dihydrochloride (CAS 1965308-85-3), a certified reference material (molecular formula C7H10BrN3HCl, MW 252.54 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine/bromine substitution, 4-Bromo-1-pyrrolidin-3-yl-1H-pyrazole dihydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.54 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.
