Quality Control

Our Cyclohexanecarboxaldehyde, 1-Methyl-2-Oxo-, (S)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure high enantiomeric excess (ee) and chemical purity. Certificates of Analysis (COA) with detailed specifications are provided to guarantee consistency and traceability for your critical R&D and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This material is easily oxidized and light-sensitive; allow the sealed container to reach ambient temperature before opening to minimize moisture condensation.
