Quality Control

Our 5-Hexen-2-One, 3,4-Dimethyl-, (R*,R*)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chiral purity analysis by GC or HPLC, to ensure consistent stereochemical integrity and chemical purity suitable for research and process development. Certificates of Analysis (COA) with detailed chromatographic data are provided to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
