Quality Control

Our 1,3-Cyclohexadiene-1-Carboxaldehyde, 4-(1-Methylethenyl)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity (typically by GC or HPLC), identity confirmation (by IR, NMR), and impurity profiles is available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
