Quality Control

Our production of 4,6-Octadien-2-One, 3-Methyl-, [S-(E,E)]- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is analyzed using advanced chromatographic (GC, HPLC) and spectroscopic (NMR, IR) techniques. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container under an inert atmosphere (e.g., nitrogen or argon), protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace and avoid prolonged exposure to air.
