Quality Control

Our 3,4-Dimethyl-1,5-Hexadiene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area 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) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and contamination.
