Quality Control

Our production of 3-Cyclohexen-1-One,2-Methyl-5-(1-Methylethyl)-,(2S,5R)-(9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high enantiomeric excess (ee). Each lot is characterized using advanced analytical techniques including chiral HPLC, GC, and NMR to confirm identity, purity, and stereochemical integrity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled 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 preservation and to minimize degradation. Keep away from heat, sparks, and open flames.
