sodium (2Z)-1-ethoxy-5-methyl-1,4-dioxohex-2-en-2-olate (CAS 746640-80-2), molecular formula C9H13O4Na and molecular weight 208.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of sodium (2Z)-1-ethoxy-5-methyl-1,4-dioxohex-2-en-2-olate (C9H13O4Na) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
