Chemical Structure

3-Bromo-4-methylpyridine CAS 3430-22-6 chemical structure

Description

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.

3-Bromo-4-methylpyridine (CAS 3430-22-6) is a high-purity analytical reference standard with the molecular formula C6H6BrN and a molecular weight of 172.02 g/mol.

Owing to a nitrile group, bromine substitution, an aromatic ring system, 3-Bromo-4-methylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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