Quality Control

Our Dimethylketene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and Infrared Spectroscopy (IR) to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and relevant physical properties is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Keep container tightly sealed when not in use to prevent moisture ingress and decomposition.
