Description

5-S-Cysteinyldopamine is a specific metabolite formed from the oxidative conjugation of dopamine with cysteine, representing a key biomarker in the study of neurodegenerative processes. This compound is of significant value in neuroscience and biochemical research for investigating oxidative stress pathways and catecholamine metabolism. It is primarily needed by research institutions, pharmaceutical R&D departments, and diagnostic kit manufacturers focused on Parkinson's disease and related neurological disorders.

Application

• Biochemical Research: Used as a reference standard and reagent in studies of dopamine metabolism and oxidative stress.
• Neuroscience Investigations: Critical for researching biomarkers associated with neurodegenerative diseases such as Parkinson's.
• Pharmaceutical Development: Serves as a key intermediate or analytical standard in drug discovery programs targeting neurological conditions.
• Diagnostic Assay Production: Employed in the development and calibration of ELISA kits and other in-vitro diagnostic tests for neurological markers.
• Metabolomics Studies: A defined metabolite for profiling and quantifying pathways in catecholamine and thiol biology.
• Toxicology Research: Used to study the neurotoxic effects of dopamine quinones and related oxidative products.

Quality Control

Our 5-S-Cysteinyldopamine is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, MS). Certificates of Analysis (COA) detailing batch-specific results are provided to ensure traceability and compliance with research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation. For long-term storage, desiccate to protect against moisture. Allow the sealed container to reach room temperature before opening to prevent condensation.
