Quality Control

Our 2-Pentanone, 3-Ethyl-4-Hydroxy-, (R*,R*)- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
