Quality Control

Every batch of 2,9-Dimethyl-5-Methylene-9-Decen-4-Ol is produced and tested under a strict quality management system to ensure batch-to-batch consistency and reliability. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
