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.
1,5-Dibromo-3-Methyl-2-[(Trifluoromethyl)Sulfinyl]Benzene (CAS 223683-76-9) is a high-purity analytical reference standard with the molecular formula C8H5Br2F3OS and a molecular weight of 365.99 g/mol.
The molecular framework of 1,5-Dibromo-3-Methyl-2-[(Trifluoromethyl)Sulfinyl]Benzene (C8H5Br2F3OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
