2,6-Diiodocyclohexa-2,5-diene-1,4-dione (CAS 20389-01-9) is a high-purity analytical reference standard with the molecular formula C6H2I2O2 and a molecular weight of 359.89 g/mol.
The molecular framework of 2,6-Diiodocyclohexa-2,5-diene-1,4-dione (C6H2I2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 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.
