Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.68 g/mol gives 3-Chloro-4-(trifluoromethylthio)aniline 3-chloro-4-trifluoromethylsulfanyl-phenylamine 3-chloro-4-trifluoromethylthioaniline 64628-74-6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-4-(trifluoromethylthio)aniline 3-chloro-4-trifluoromethylsulfanyl-phenylamine 3-chloro-4-trifluoromethylthioaniline 64628-74-6 (CAS 64628-74-6), molecular formula C7H11ClF3NS and molecular weight 233.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-4-(trifluoromethylthio)aniline 3-chloro-4-trifluoromethylsulfanyl-phenylamine 3-chloro-4-trifluoromethylthioaniline 64628-74-6 (C7H11ClF3NS) is characterized by sulfur-containing functionality, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
