Chemical Structure

3,4,5-Tribromopyridin-2-amine CAS 856848-75-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3,4,5-Tribromopyridin-2-amine (CAS 856848-75-4), molecular formula C5H3Br3N2 and molecular weight 330.80 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, bromine substitution, 3,4,5-Tribromopyridin-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.80 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).

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.
