Product Overview:
N-Phthaloyl-L-Glutamic Acid is a common N-protected amino acid derivative. It features a phthaloyl (PHT) protecting group on the amino group of L-glutamic acid, making it widely used in peptide synthesis and organic chemistry to prevent side reactions during coupling.
Applications:
  • Key building block for peptide synthesis and pharmaceutical intermediate manufacturing
  • Used in the synthesis of complex peptides, API intermediates, and chiral compounds
  • Applied in the development of new synthetic routes for amino acid derivatives
Additional Information:
  • Full analytical documentation (¹H NMR, LC-MS, chiral HPLC, elemental analysis) available upon request
  • Custom synthesis and bulk production quantities are available
  • For research and laboratory use only; not intended for direct human administration.
