Chemical Structure
Description
3-(4-Bromo-2-fluorophenyl)pyridine (CAS 1187163-18-3) is a high-purity analytical reference standard with the molecular formula C11H7BrFN and a molecular weight of 252.08 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution, 3-(4-Bromo-2-fluorophenyl)pyridine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-(4-Bromo-2-fluorophenyl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
