Chemical Structure
Description
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.
4-Bromo-6-phenyldibenzo[b,d]thiophene (CAS 1415844-67-5), molecular formula C18H11BrS and molecular weight 339.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, bromine substitution, a polycyclic aromatic system, 4-Bromo-6-phenyldibenzo[b,d]thiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.25 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.
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.
