Quality Control

Our 1,2-Ethanedione is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and concentration. Certificates of Analysis (COA) documenting these results are provided to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep containers sealed and under appropriate conditions to maintain stability and prevent concentration changes.
