Chemical Structure
Description
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.
2,4-Difluoro-1-[(Trifluoromethyl)Sulfinyl]Benzene (CAS 223683-75-8), molecular formula C7H3F5OS and molecular weight 230.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Difluoro-1-[(Trifluoromethyl)Sulfinyl]Benzene (C7H3F5OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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.
