8-Hydroxy-4-oxo-4H-chromene-2-carboxylic acid CAS 129472-71-5

Description

The occurrence of 8-Hydroxy-4-oxo-4H-chromene-2-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

8-Hydroxy-4-oxo-4H-chromene-2-carboxylic acid (CAS 129472-71-5), molecular formula C10H6O5 and molecular weight 206.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 8-Hydroxy-4-oxo-4H-chromene-2-carboxylic acid (C10H6O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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).
