Ethyl 3-(6-chloro-2-oxo-2H-chromen-3-yl)-3-oxopropanoate (CAS 400084-50-6) is a high-purity analytical reference standard with the molecular formula C14H11ClO5 and a molecular weight of 294.69 g/mol.

The molecular framework of Ethyl 3-(6-chloro-2-oxo-2H-chromen-3-yl)-3-oxopropanoate (C14H11ClO5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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).

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), Ethyl 3-(6-chloro-2-oxo-2H-chromen-3-yl)-3-oxopropanoate 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.
