Quality Control

Our Acetaldehyde, o-[(2Z)-3-Hydroxy-1-Oxo-2-Butenyl]Oxime, (1E)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistent chemical identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
