Description

D-Tyrosine Benzyl Ester is a protected derivative of the non-essential amino acid D-Tyrosine, where the carboxylic acid group is esterified with benzyl alcohol. This modification enhances its lipophilicity and stability, making it a crucial chiral building block and intermediate in sophisticated organic synthesis. It is primarily utilized by research institutions and manufacturers in the pharmaceutical and biotechnology sectors for the development of peptide-based therapeutics, enzyme inhibitors, and other bioactive compounds.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for peptide drugs and enzyme inhibitors.
• Peptide Synthesis: Used in solid-phase and solution-phase peptide synthesis (SPPS) to incorporate the D-Tyrosine residue, which can confer metabolic stability and alter biological activity in therapeutic peptides.
• Biochemical Research: Employed as a substrate or inhibitor in enzymatic studies and as a standard in analytical method development for chiral separation techniques like HPLC.
• Proteomics & Diagnostics: Acts as a building block for synthesizing labeled peptides and probes used in mass spectrometry, imaging, and diagnostic assay development.
• Material Science: Potential use as a monomer or precursor for designing novel biomimetic polymers and functional materials.

Quality Control

Our D-Tyrosine Benzyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and pharmaceutical applications. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
