Description

4-Amino-L-Phenylalanine is a non-proteinogenic amino acid derivative of L-phenylalanine, featuring an amino group substitution at the para position of the aromatic ring. This structural modification makes it a valuable chiral building block and intermediate for the synthesis of complex bioactive molecules. It is essential for research and production in advanced pharmaceutical and fine chemical sectors. Key industries requiring this high-purity intermediate include pharmaceutical development, peptide synthesis, and biochemical research.

Application

• Pharmaceutical Intermediate: A critical chiral precursor in the synthesis of novel drug candidates, including enzyme inhibitors and receptor modulators.
• Peptide Synthesis: Used as a modified amino acid residue to introduce specific functional groups into synthetic peptides for research and therapeutic applications.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies and as a standard in analytical method development.
• Fine Chemical Synthesis: Employed in the preparation of complex organic molecules, dyes, and advanced materials requiring a para-aminophenylalanine moiety.
• Agrochemical Research: Acts as a building block for developing new compounds with potential biological activity.
