Chemical Structure
Description
Sodium 1-ethoxy-1,2,4-trioxopentan-3-ide (CAS 6887-74-7), molecular formula C7H9O4Na and molecular weight 180.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium 1-ethoxy-1,2,4-trioxopentan-3-ide (C7H9O4Na) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Sodium 1-ethoxy-1,2,4-trioxopentan-3-ide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
