Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 255.54 g/mol gives 4-Bromo-3-chloro-2-fluorothioanisole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-3-chloro-2-fluorothioanisole (CAS 214057-25-7) is a high-purity analytical reference standard with the molecular formula C7H5BrClFS and a molecular weight of 255.54 g/mol.
Structurally, 4-Bromo-3-chloro-2-fluorothioanisole (C7H5BrClFS) contains sulfur-containing functionality, fluorine/chlorine/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 255.54 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
