5-(4-Bromo-2-fluorophenyl)-2-methylpyridine CAS 1187163-44-5

Description

Compared with other compounds in its class, the molecular weight of 266.11 g/mol gives 5-(4-Bromo-2-fluorophenyl)-2-methylpyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(4-Bromo-2-fluorophenyl)-2-methylpyridine (CAS 1187163-44-5), molecular formula C12H9BrFN and molecular weight 266.11 g/mol, is a CATO reference standard with documented purity and traceability.

5-(4-Bromo-2-fluorophenyl)-2-methylpyridine (C12H9BrFN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 5-(4-Bromo-2-fluorophenyl)-2-methylpyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
