Quality Control

Our 2,3-Pentanedione, 4-Methyl-, 3-Oxime, (E)- (9Ci) is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, impurities, and physical properties are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
