D-Pyroglutamic acid Chemical Properties,Uses,Production
Chemical Properties
white to light yellow crystal powdeUses
Serves as a building block in the synthesis of diphthamideDefinition
ChEBI: The D-enantiomer of 5-oxoproline.Purification Methods
Purify R-pyroglutamic acid by dissolving it in H2O, filtering, passing the filtrate through Dowex 50 (H+ form), washing with H2O, pooling washings, evaporating, removing H2O azeotropically with Me2CO and *C6H6, washing the residue with Et2O and recrystallising from EtOH/pet ether.
