Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Pentanoic acid, 5,5,5-trifluoro-2-(hydroxyimino)-4-(trifluoromethyl)-, ethyl ester (CAS 1956426-81-5) is a high-purity analytical reference standard with the molecular formula C8H9F6NO3 and a molecular weight of 281.15 g/mol.
Pentanoic acid, 5,5,5-trifluoro-2-(hydroxyimino)-4-(trifluoromethyl)-, ethyl ester (C8H9F6NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), Pentanoic acid, 5,5,5-trifluoro-2-(hydroxyimino)-4-(trifluoromethyl)-, ethyl ester 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.
