Chemical Structure
Description
The molecular framework of 6131-98-2 S66F32Y3ZO Sodium bitartrate monohydrate UNII-S66F32Y3ZO Butanedioic acid, 2,3-dihydroxy- (2R,3R)-, sodium salt, hydrate (1:1:1) Sodium acid tartrate monohydrate Sodium ditartrate hydrogen Tartaric acid, monosodium salt, monohydrate (C4H5O6NaH2O) 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.
