[Chemical Properties]

Diethyl glutamate is a viscous liquid. B,P. 239° C. Very soluble in water, soluble in alcohol and most perfume oils. Very faint, winey-ethereal odor. In high concentration somewhat bitter taste, in weaker solutions rather sweet, bland, nondescript taste.
[Uses]

Diethyl glutamate has been attributed synergistic effect upon fragrance mixtures (perfume compositions, etc.). A French patent covers its use as a fragrance-enhancing additive, but experiments seem to confirm that the material is not a universal synergist.
[Preparation]

From L-alpha-Glutamic acid, by esterification.
