Chemical Structure
Description
1,1,1-Trifluoro-2-(methylsulfanyl)ethane (CAS 5187-55-3), molecular formula C3H5F3S and molecular weight 130.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1,1-Trifluoro-2-(methylsulfanyl)ethane (C3H5F3S) is characterized by sulfur-containing functionality, fluorine substitution. 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.
