What is D-2-Phenylglycine?

D-2-Phenylglycine has too many other names, such as D-Phenylglycine, D-(-)-Phenylglycine, D(-)-alpha-Phenylglycine, D-(-)-Α-Phenylglycine, etc. Almost different manufacturers or suppliers use different names. Many Chinese suppliers use D-Phenylglycine. However, in our opinion, D-2-Phenylglycine is a more popular standard name for international readers and buyers.


D-2-Phenylglycine applications

D-2-Phenylglycine is widely used in the daily life and production. Its applications include:

1. To produce semisynthetic cephalosporin, such as cephalexin, cefaclox, ampicillin, Finn La Kappa, and intermediates to produce synthesize other lactam antibiotics, such as L-phenylglycine chloride hydrochloride.

2. To produce ampicillin, piperacillin, azlocillin, cefroxadine.

3. As the important organic intermediate, D-Phenylglycine is also frequently used to produce veterinary drugs.

However, D-2-Phenylglycine is not the only raw material for synthesizing ampicillin and cephalexin. DL-Phenylglycine and L-Phenylglycine are 2 other raw materials for the same purpose. Their CAS numbers and chemical properties are different. Please pay attention in the procurement process.

Please see the info for the other 2 products below:
