Quality Control

Our 5-Hexene-2,3-Dione, 5-Methyl-, 3-Oxime (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality attributes. Our quality systems are designed to support cGMP and ISO standards for customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled 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.
