| | D-2-Phenylglycine Usage And Synthesis |
| 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.
