The molecular framework of 2-I feminineIi paragraph signthornEaAAE paragraph signthornO feminine E(R) masculineIIi 2-No uIi paragraph signthornEa paragraph signthornAAENI E(R) masculineIIi 2-Oxopentanedioic acid disodium salt 305-72-6 Sodium 2-oxoglutarate dibasic dihydrate dipotassium dihydrate oxoglutarate disodium dihydrate |A ketoglutarate (C5H4O5NaH2O) is characterized by a carbohydrate-derived structure. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
