N-Acetyl-L-phenylalanine Usage And Synthesis
  • Chemical Propertieswhite to off-white fine cryst. powder or needles
  • DefinitionChEBI: The N-acetyl derivative of L-phenylalanine.
  • Purification MethodsN-Acetyl-L-phenylalanine is recrystallised from H2O, 20% MeOH/H2O, or CHCl3; dry and store it at 4o. The (DL)-isomer crystallises from H2O, Me2CO, EtOAc, or CHCl3 with m 152-154o and the solubilities in w% at 25o are 0.73 (H2O), 4.3 (Me2CO), 0.79 (EtOAc) and 0.34 (CHCl3) [Kerr & Niemann J Org Chem 23 893 1958, Overby & Ingersoll J Am Chem Soc 73 3363 1951, L: Fu et al. J Am Chem Soc 76 6057 1954, Bender & Glasson J Am Chem Soc 81 1591 1959]. [Beilstein 14 I 238, 4 IV 1575.]
