Description
CATO manufactures (E)-4,4,4-trifluorobut-2-enamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies (E)-4,4,4-trifluorobut-2-enamide (CAS 590-76-1), a certified reference material (molecular formula C4H4F3NO, MW 139.08 g/mol) for analytical method development and quality control.
The molecular framework of (E)-4,4,4-trifluorobut-2-enamide (C4H4F3NO) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
