D-Pyroglutamic acid Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystal powde

Uses

Serves as a building block in the synthesis of diphthamide

Definition

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.
