Quality Control

Every batch of our 3-Methyl-1,3-pentadiene is produced and tested under stringent quality management protocols to ensure high purity and consistency. We provide comprehensive analytical data, including Gas Chromatography (GC) analysis, to verify identity and assay. A Certificate of Analysis (COA) detailing all relevant specifications is available for each shipment upon request, supporting your quality assurance and regulatory compliance needs.

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 or argon) for long-term stability. Recommended storage temperature is 2-8°C.
