Description

D-Dopa is the D-enantiomer of the amino acid 3,4-dihydroxyphenylalanine, a crucial chiral building block and reference standard in advanced pharmaceutical and biochemical research. Its distinct stereochemistry makes it an essential tool for studying enzyme specificity, developing chiral separation methods, and synthesizing specialized compounds where the D-configuration is required. This high-purity material is primarily targeted at research institutions, pharmaceutical R&D departments, and fine chemical manufacturers engaged in enantioselective synthesis and neurological studies.

Application

• Pharmaceutical Research & Development: Serves as a critical chiral intermediate and reference standard in the synthesis and study of enantiomerically pure drugs, particularly in neurological and metabolic research.
• Biochemical Studies: Used as a substrate or inhibitor in enzymatic assays to investigate the activity and stereospecificity of enzymes like DOPA decarboxylase and tyrosine hydroxylase.
• Chiral Resolution & Analysis: Employed as a standard for developing and validating analytical methods (e.g., chiral HPLC) to separate and quantify enantiomers of dopa and related compounds.
• Fine Chemical Synthesis: Acts as a key starting material or building block for the preparation of more complex chiral molecules, peptides, and proprietary compounds in specialized organic synthesis.
• Neuroscience Research: Utilized in experimental models to study dopaminergic pathways, receptor interactions, and the biochemical basis of various neurological conditions, contrasting with the effects of its L-enantiomer.

Quality Control

Our D-Dopa is manufactured under strict quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to meet the exacting standards required for research and synthesis. A Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and specific test results is provided with every shipment to support your quality assurance protocols.

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 sensitivity to oxidation, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep the container tightly sealed in a dry environment to minimize exposure to atmospheric moisture.
