3,5-Dibromo-2,4-difluorothiophenol CAS 1803783-69-8

Description

Owing to sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system, 3,5-Dibromo-2,4-difluorothiophenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.95 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.

3,5-Dibromo-2,4-difluorothiophenol (CAS 1803783-69-8) is a high-purity analytical reference standard with the molecular formula C6H2Br2F2S and a molecular weight of 303.95 g/mol.

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.

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.
