Quality Control

Our production of 3-Cyclohexene-1-Carboxaldehyde, 2-Methoxy-1-Methyl-, (1S-Trans)- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high enantiomeric purity. All materials are characterized using advanced analytical techniques including chiral HPLC, GC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with each shipment, supporting compliance with research and cGMP guidelines where applicable.

Storage

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