D-2-Phenylglycine Chemical Properties,Uses,Production

Description

L-phenylglycine (Cephalexin EP Impurity A) is a derivative of glycine, a non-essential amino acid for human development. Glycine is an inhibitory neurotransmitter in the spinal cord and an allosteric modulator of NMDA receptors.

Storage

Store at room temperature. Store in cool dry place in tightly closed container. Store away from oxidizing agent.

Description

d-Phenylglycine is widely used in large quantity as the side chain that makes ampicillin and cephalexin orally acceptable.

Chemical Properties

White crystalline powder

Uses

D-(-)-2-Phenylglycine (Cefalexin EP Impurity A) is the derivative of glycine (G615990), a non-essential amino acid for human development. Glycine is an inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA receptors.

Uses

D-(-)-2-Phenylglycine is the derivative of glycine (G615990), a non-essential amino acid for human development. Glycine is an inhibitory neurotransmitter in spinal cord, allosteric regulator of NMDA r eceptors.

Definition

ChEBI: The R stereoisomer of alpha-phenylglycine.

Flammability and Explosibility

Non flammable

Synthesis

Industrially, dphenylglycine has been produced by a conventional resolution method or by kinetic resolution with acylase. Another enzymatic procedure has been developed by Yamada et al. , as shown below.
