Quality Control

Our (2E,4E)-3,4-Dimethylhexa-2,4-Diene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and isomeric integrity. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee supply reliability 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 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 or argon) at temperatures between 2°C and 8°C for long-term stability. Keep away from strong oxidizing agents.
