Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-3,4,5,6-tetrafluorobenzenethiol (CAS 2773501-50-9) is a high-purity analytical reference standard with the molecular formula C6HBrF4S and a molecular weight of 261.03 g/mol.
Structurally, 2-Bromo-3,4,5,6-tetrafluorobenzenethiol (C6HBrF4S) contains sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 261.03 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
