Ethyl 4-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-4-oxobutanoate (CAS 951889-31-9) is a high-purity analytical reference standard with the molecular formula C14H16O5 and a molecular weight of 264.27 g/mol.
The molecular framework of Ethyl 4-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-4-oxobutanoate (C14H16O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Ethyl 4-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-4-oxobutanoate 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.
