Quality Control

Our 4-Methyl-4-Undecene is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for extended stability.
