1,2,3-Trichloro-6-fluorodibenzo[b,d]furan CAS 669767-00-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2,3-Trichloro-6-fluorodibenzo[b,d]furan.

1,2,3-Trichloro-6-fluorodibenzo[b,d]furan (CAS 669767-00-4) is a high-purity analytical reference standard with the molecular formula C12H4Cl3FO and a molecular weight of 289.52 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 1,2,3-Trichloro-6-fluorodibenzo[b,d]furan is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.52 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.

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.
