Chemical Structure

4-Bromo-2-fluoro-6-methylbenzonitrile CAS 1427438-75-2 chemical structure

Description

The occurrence of 4-Bromo-2-fluoro-6-methylbenzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromo-2-fluoro-6-methylbenzonitrile (CAS 1427438-75-2) is a high-purity analytical reference standard with the molecular formula C8H5BrFN and a molecular weight of 214.03 g/mol.

Based on its molecular formula C8H5BrFN, 4-Bromo-2-fluoro-6-methylbenzonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 4-Bromo-2-fluoro-6-methylbenzonitrile 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.
