Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-Ethoxy-1,1-difluorobut-3-en-2-one.
(E)-4-Ethoxy-1,1-difluorobut-3-en-2-one (CAS 285135-89-9), molecular formula C6H8F2O2 and molecular weight 150.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-4-Ethoxy-1,1-difluorobut-3-en-2-one (C6H8F2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
CATO manufactures (E)-4-Ethoxy-1,1-difluorobut-3-en-2-one 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.
