Quality Control

Our 7-Methyl-3-(1-methylethyl)-1,5-octadiene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee 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 (store under inert atmosphere), it is recommended to keep the container under an inert gas blanket (e.g., nitrogen or argon) after opening and to minimize headspace. Recommended storage temperature is 2-8°C for extended stability.
