Chemical Structure

2,3,4,6,7-Pentachlorodibenzo[b,d]furan CAS 57117-43-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3,4,6,7-Pentachlorodibenzo[b,d]furan.

CATO supplies 2,3,4,6,7-Pentachlorodibenzo[b,d]furan (CAS 57117-43-8), a certified reference material (molecular formula C12H3Cl5O, MW 340.42 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,3,4,6,7-Pentachlorodibenzo[b,d]furan is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.42 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.

CATO manufactures 2,3,4,6,7-Pentachlorodibenzo[b,d]furan under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
