Quality Control

Every batch of our 2(3H)-Furanone, 3-Acetyldihydro-3-Methyl-4-Methylene-, (3R)- (9Ci) undergoes rigorous analytical testing to ensure it meets the high standards required for synthetic applications. Our quality assurance protocol includes chiral purity analysis (enantiomeric excess), chemical identity confirmation, and quantification of key impurities. A comprehensive Certificate of Analysis (COA) detailing assay, chiral purity, and related substances is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage and handling.
