Quality Control

Our 4-Methyl-1,5-Heptadiene is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, consistency, and compliance with your technical requirements.

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) and at temperatures between 2°C and 8°C for extended stability. Keep away from strong oxidizing agents.
