Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 221.09 g/mol gives 4-Bromo-2-fluorothioanisole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Bromo-2-fluorothioanisole (CAS 221030-79-1), a certified reference material (molecular formula C7H6BrFS, MW 221.09 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H6BrFS, 4-Bromo-2-fluorothioanisole contains sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
