Description

D-Tyrosine, 3-Hydroxy-, Ethyl Ester (9Ci) is a specialized, non-proteinogenic amino acid derivative with a protected carboxyl group. This compound is a valuable chiral building block and intermediate in advanced organic synthesis, particularly for the development of pharmaceuticals and bioactive molecules. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require high-purity, structurally defined intermediates for complex synthesis.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in peptide mimetics and enzyme inhibitors.
• Biochemical Research: Used as a precursor or standard in metabolic pathway studies, enzyme-substrate interaction analysis, and proteomics research.
• Agrochemical Synthesis: Serves as a building block for creating advanced, targeted crop protection agents with specific chiral activity.
• Fine Chemical Production: Employed in the synthesis of complex organic molecules, dyes, and specialty polymers where precise stereochemistry is required.
• Peptide Chemistry: Useful in solid-phase peptide synthesis (SPPS) and the preparation of modified peptides with enhanced stability or biological activity.
