Chemical Structure
Description
CATO supplies 8-Fluoro-1,4-dioxaspiro[4.5]dec-7-ene (CAS 142273-44-7), a certified reference material (molecular formula C8H11FO2, MW 158.17 g/mol) for analytical method development and quality control.
8-Fluoro-1,4-dioxaspiro[4.5]dec-7-ene (C8H11FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 8-Fluoro-1,4-dioxaspiro[4.5]dec-7-ene 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.
