1,2,6,9-Tetrachlorodibenzo[b,d]thiophene CAS 134705-53-6

Description

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.

1,2,6,9-Tetrachlorodibenzo[b,d]thiophene (CAS 134705-53-6) is a high-purity analytical reference standard with the molecular formula C12H4Cl4S and a molecular weight of 322.04 g/mol.

1,2,6,9-Tetrachlorodibenzo[b,d]thiophene (C12H4Cl4S) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
