| Biological activity | 2-Phenylglycine (DL-α-Phenylglycine) is a metabolite in breast milk during lactation from W2 to W4. |
| use | intermediates of cephalexin and cefaclor. Used to make L-phenylglycine |
| production method | benzaldehyde is cyclized, hydrolyzed and neutralized to obtain the product. Put the solution of ammonia bicarbonate and sodium cyanide into the reaction pot, drip benzaldehyde under stirring, and heat preservation at 75-80 ℃ for 3 hours to obtain phenylhydantoin. Pump into an autoclave, add sodium hydroxide solution, raise the temperature, empty the ammonia gas generated by the reaction for 1h, and then hydrolyze at 130-160 ℃ for 3h. Feeding, adding HCl to neutralize until pH = 6-7, centrifugally spin dry to obtain DL-2-phenylglycine. There is also a glyoxylic acid route, which can reduce production costs and solve the problem of high toxicity of traditional process raw materials. |
