Description

Arsenobetaine is a non-toxic, organoarsenic compound that serves as the primary form of arsenic found in marine organisms. This compound is of critical importance as a certified reference material and analytical standard for accurate speciation analysis in food safety and environmental monitoring. It is essential for laboratories and research institutions focused on toxicology, seafood safety compliance, and studying arsenic biogeochemical cycles to distinguish between harmful inorganic arsenic and benign organic forms.

Application

• Certified Reference Material (CRM) for the calibration of analytical instruments in arsenic speciation studies.
• Primary analytical standard for quantifying arsenobetaine content in seafood (e.g., fish, shellfish, algae) to ensure food safety compliance.
• Critical reagent in environmental monitoring to track arsenic species in marine and aquatic ecosystems.
• Essential component in clinical and toxicological research to understand arsenic metabolism and human exposure pathways.
• Used in the development and validation of analytical methods, including HPLC-ICP-MS and HPLC-ESI-MS.
• Quality control standard for testing laboratories to verify the accuracy of arsenic speciation analyses.

Quality Control

Our Arsenobetaine is produced and handled under strict quality management protocols to ensure the highest purity and consistency required for reference standards. Each batch undergoes comprehensive analysis, including identity confirmation by spectroscopic methods and purity assessment by chromatographic techniques. A detailed Certificate of Analysis (COA) is provided, confirming compliance with in-house specifications tailored for analytical and research applications.

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. For long-term stability, consider storage under inert atmosphere or desiccant.
