Quality Control

Our (2S-Cis)-2-(2,2,3-Trimethyl-4-Oxocyclentyl)Ethyl Acetate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure high enantiomeric excess (ee) and chemical purity. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen or argon blanket). Keep away from heat, sparks, and open flame.
