Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.34 g/mol gives 2-Bromo-3,4,6-trichlorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-3,4,6-trichlorophenol (CAS 70757-44-7) is a high-purity analytical reference standard with the molecular formula C6H2BrCl3O and a molecular weight of 276.34 g/mol.
Structurally, 2-Bromo-3,4,6-trichlorophenol (C6H2BrCl3O) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 276.34 g/mol, it falls into the medium-molecular-weight range. 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).
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.
