Quality Control

Our Mannurono-γ-Lactone is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and development. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance.
