Chemical Structure
Description
Ethyl 4-bromo-3-ethoxybut-2-enoate (CAS 1116-50-3), molecular formula C8H13BrO3 and molecular weight 237.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 4-bromo-3-ethoxybut-2-enoate (C8H13BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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 Ethyl 4-bromo-3-ethoxybut-2-enoate 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.
