Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.01 g/mol gives 4-Bromo-2,6-difluoro-3-methylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2,6-difluoro-3-methylphenol (CAS 1365272-26-9) is a high-purity analytical reference standard with the molecular formula C7H5BrF2O and a molecular weight of 223.01 g/mol.
4-Bromo-2,6-difluoro-3-methylphenol (C7H5BrF2O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
