Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-[(2-bromoethyl)sulfanyl]-2,4-difluorobenzene (CAS 1097824-30-0), molecular formula C8H7BrF2S and molecular weight 253.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(2-bromoethyl)sulfanyl]-2,4-difluorobenzene (C8H7BrF2S) is characterized by sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
