Quality Control

Our 4-Methyl-2,3-pentanedione is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or equivalent light-blocking material until use.
