Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.43 g/mol gives 2-Bromo-5-chloro-3-fluoropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-5-chloro-3-fluoropyridine (CAS 514797-97-8) is a high-purity analytical reference standard with the molecular formula C5H2BrClFN and a molecular weight of 210.43 g/mol.
2-Bromo-5-chloro-3-fluoropyridine (C5H2BrClFN) contains a nitrile group, fluorine/chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
