Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.67 g/mol gives 1-[(2-chloroethyl)sulfanyl]-4-fluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[(2-chloroethyl)sulfanyl]-4-fluorobenzene (CAS 5323-03-5) is a high-purity analytical reference standard with the molecular formula C8H8ClFS and a molecular weight of 190.67 g/mol.
The molecular framework of 1-[(2-chloroethyl)sulfanyl]-4-fluorobenzene (C8H8ClFS) is characterized by sulfur-containing functionality, fluorine/chlorine 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. 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.
