Quality Control

Our 4-Methyl-2-Penten-1-Ol is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and compliance with agreed specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and available upon request.

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 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 moisture ingress.
