Chemical Structure
Description
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.
CATO supplies (E)-1,1,1-Trifluoro-4-(furan-2-yl)but-3-en-2-one (CAS 202074-24-6), a certified reference material (molecular formula C8H5F3O2, MW 190.12 g/mol) for analytical method development and quality control.
(E)-1,1,1-Trifluoro-4-(furan-2-yl)but-3-en-2-one (C8H5F3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
