Quality Control

Our 1,1-Diisopropylethylene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C. Keep the container tightly sealed in a cool, dry, well-ventilated place away from heat, sparks, and open flames.
