Quality Control

Our 2(4H)-Benzofuranone, 5,6-Dihydro-3,6-Dimethyl-, (6R)- is manufactured under strict quality control protocols to ensure high chemical purity and enantiomeric excess (ee). Each batch is tested using advanced analytical techniques including HPLC, GC, and chiral analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, assay, chiral purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed and may require storage under an inert atmosphere for long-term preservation. Keep away from incompatible materials.
