Quality Control

Our 1,2:5,6-Di-o-Cyclohexylidene-D-Mannitol is manufactured under strict quality management systems. Products undergo rigorous analytical testing, including HPLC, NMR, and chiral purity analysis, to ensure compliance with high-purity standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each batch.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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 product stability and performance.
