Quality Control

Our production of Ethanone, 1-(1,2,2-Trimethylcyclopentyl)-, (R)- (9Ci) adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including chiral purity analysis by GC or HPLC, to ensure it meets exacting customer specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and optical rotation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). 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 stability and to minimize degradation.
