Description

D-Tyrosine, o-Ethyl- (9Ci) is a chemically modified derivative of the amino acid tyrosine, characterized by an ethyl group substitution on the phenolic oxygen. This structural modification makes it a valuable chiral building block and intermediate for advanced organic synthesis. It is primarily utilized by research institutions and industrial R&D departments focused on pharmaceuticals, agrochemicals, and specialty chemical development.

Application

• Pharmaceutical Intermediate: Serves as a key chiral precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for neurological and metabolic research.
• Agrochemical Research: Used in the development of new herbicides, pesticides, and plant growth regulators that leverage its tyrosine-based structure.
• Peptide Synthesis: Acts as a protected or modified tyrosine analog in the solid-phase and solution-phase synthesis of specialized peptides and peptidomimetics.
• Biochemical Research: Employed as a substrate or inhibitor in enzymatic studies to investigate tyrosine kinase and phosphatase activity.
• Material Science: Explored as a monomer or cross-linking agent for creating novel bio-inspired polymers and functional materials.
• Diagnostic Reagent Development: Utilized in the design and synthesis of fluorescent probes, tracers, and contrast agents for medical imaging.

Quality Control

Our D-Tyrosine, o-Ethyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing identity, purity, and specific test results 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). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and handling properties.
