Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(1-Cyclohexyl-2,2,2-trifluoroethyl)benzene (CAS 73899-23-7), molecular formula C14H17F3 and molecular weight 242.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-Cyclohexyl-2,2,2-trifluoroethyl)benzene (C14H17F3) is characterized by fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
