Chemical Structure
Description
2-Chloro-3,3,3-trifluoro-2-(trifluoromethyl)propanoyl chloride (CAS 662-19-1), molecular formula C4Cl2F6O and molecular weight 248.94 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-3,3,3-trifluoro-2-(trifluoromethyl)propanoyl chloride (C4Cl2F6O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine 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.
