Common_NameErythrono-1,4-lactone
DescriptionErythrono-1,4-lactone has been identified as the lactone of tetronic acid in urine from normal adults and neonates. Lactonization is a potential problem when measuring acids that contain a hydroxyl group at the number 4 carbon, as lactones are formed under acidic conditions. Evidence indicates that the 4-hydroxy acids being investigated do not normally exist to any appreciable extent as lactones in urine, the general anion-exchange procedure involved oxime derivatization (of keto acids) under basic conditions that would surely hydrolyze lactones before they were processed on the column.
