4-Hydroxy-2-oxo-2H-pyran-6-carbaldehyde (CAS 147647-75-4), molecular formula C6H4O4 and molecular weight 140.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Hydroxy-2-oxo-2H-pyran-6-carbaldehyde (C6H4O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
