1,2,8,9-Tetrachlorodibenzo[b,d]thiophene CAS 134705-54-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2,8,9-Tetrachlorodibenzo[b,d]thiophene.

1,2,8,9-Tetrachlorodibenzo[b,d]thiophene (CAS 134705-54-7) is a high-purity analytical reference standard with the molecular formula C12H4Cl4S and a molecular weight of 322.04 g/mol.

Owing to sulfur-containing functionality, chlorine substitution, an aromatic ring system, 1,2,8,9-Tetrachlorodibenzo[b,d]thiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.04 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.

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.
