Quality Control

Our production of Cyclohexanecarboxaldehyde, 2-Methyl-3-Oxo-, trans- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, identity confirmation by IR and NMR spectroscopy, and quantification of key impurities. We provide detailed Certificates of Analysis (COA) with every shipment, ensuring full traceability and compliance with your research or production specifications.

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 a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under an inert gas blanket for long-term stability.
