Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.26 g/mol gives Cyclooct-1-en-1-yl trifluoromethanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cyclooct-1-en-1-yl trifluoromethanesulfonate (CAS 28075-35-6) is a high-purity analytical reference standard with the molecular formula C9H13F3O3S and a molecular weight of 258.26 g/mol.
The molecular framework of Cyclooct-1-en-1-yl trifluoromethanesulfonate (C9H13F3O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
