Quality Control

Our n-(+)-Biotinyl-3-Aminopropylammonium Tri is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and pharmaceutical applications. Certificates of Analysis (COA) with detailed batch-specific data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic nature, the container must be kept tightly sealed in a desiccated environment to prevent moisture absorption and decomposition. For long-term storage, consider storing under an inert atmosphere.
