Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 271.53 g/mol gives 1,4,6-Trichlorodibenzofuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,4,6-Trichlorodibenzofuran (CAS 82911-60-2) is a high-purity analytical reference standard with the molecular formula C12H5Cl3O and a molecular weight of 271.53 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1,4,6-Trichlorodibenzofuran is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 271.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
