Quality Control

Every batch of 3-Undecene is produced and tested under a strict quality management system to ensure consistency and reliability. Our products undergo rigorous quality testing, including GC analysis, to ensure compliance with industry standards and customer specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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 properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container under an inert gas blanket such as nitrogen and at temperatures between 2°C and 25°C. Keep away from strong acids and organic solvents.
