Quality Control

Our trans-2,2-Dimethyl-3-Hexene is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to prevent evaporation and degradation. Recommended storage temperature: 2-8°C (refrigerated) for optimal stability.
