Quality Control

Our 2,3-Undecadione is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous specifications, including identity confirmation, assay, and impurity profiling. A Certificate of Analysis (COA) documenting purity (typically ≥98% by GC), physical properties, and safety data is provided with every shipment to support your quality assurance protocols.

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). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere such as nitrogen. Keep away from heat, sparks, and open flame.
