Quality Control

Our 8-Methyl-1-undecene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including gas chromatography (GC), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with customer specifications.

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) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and contamination.
