Chemical Structure
Description
2,3-Dibromo-4,5-difluorothiophenol (CAS 1803715-74-3), molecular formula C6H2Br2F2S and molecular weight 303.95 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dibromo-4,5-difluorothiophenol (C6H2Br2F2S) contains sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
