Quality Control

Our (R,R)-(-)-N,N'-Bis(3,5-Di-tert-Butylsalicylidene)-1,2-Cyclohexanediamino-Manganese(III) Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity (enantiomeric excess) verification, to ensure consistent performance and high catalytic efficiency. Certificates of Analysis (COA) detailing assay, identity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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 hygroscopic and easily oxidized nature, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from incompatible materials.
