Quality Control

Our Isoleucylcysteine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification by IR and NMR, purity determination by HPLC, and specific tests for related substances and residual solvents. A Certificate of Analysis (COA) detailing all specifications and results is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers. Keep away from strong oxidizing agents.
