Quality Control

Our 2-Heptanone, 5-Methyl-3-Methylene-, (S)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality. Recommended storage temperature is 2-8°C.
