Quality Control

Our 2,3:5,6-Di-o-Cyclohexylidene-D-Mannolactone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity confirmation and identity verification by spectroscopic methods, to ensure it meets the specified 98% minimum purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
