Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Cyclohept-1-en-1-yl trifluoromethanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Cyclohept-1-en-1-yl trifluoromethanesulfonate (CAS 28075-51-6), molecular formula C8H11F3O3S and molecular weight 244.23 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Cyclohept-1-en-1-yl trifluoromethanesulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
