Quality Control

Our Calisto-Lactone is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including chromatographic and spectroscopic methods, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment. We adhere to cGMP principles where applicable to support its use in regulated industries.

Storage

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