Compared with other compounds in its class, the molecular weight of 314.40 g/mol gives 2,6-Dibromo-4-chloro-3,5-dimethylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Dibromo-4-chloro-3,5-dimethylphenol (CAS 175204-32-7), molecular formula C8H7Br2ClO and molecular weight 314.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 2,6-Dibromo-4-chloro-3,5-dimethylphenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
