Chemical Structure
Description
Owing to a nitrile group, chlorine/bromine substitution, 3-Bromo-5-hydrazinylpyridine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO supplies 3-Bromo-5-hydrazinylpyridine hydrochloride (CAS 28741-22-2), a certified reference material (molecular formula C5H6BrN3HCl, MW 224.49 g/mol) for analytical method development and quality control.
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.
