Compared with other compounds in its class, the molecular weight of 231.03 g/mol gives 3-Bromo-2-(trifluoromethyl)thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2-(trifluoromethyl)thiophene (CAS 924818-17-7), molecular formula C5H2BrF3S and molecular weight 231.03 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Bromo-2-(trifluoromethyl)thiophene (C5H2BrF3S) contains sulfur-containing functionality, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 231.03 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).
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.
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.
