Chemical Structure
Description
3,5-Dibromo-2-(trifluoromethyl)pyridine (CAS 436799-35-8) is a high-purity analytical reference standard with the molecular formula C6H2Br2F3N and a molecular weight of 304.89 g/mol.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, 3,5-Dibromo-2-(trifluoromethyl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.89 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.
