Quality Control

Our (5R,10R)-10-Methyl-6-Methylene-2-Isopropylidenespiro[4.5]Dec-7-Ene is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including chiral HPLC, GC, and NMR, to ensure high chemical and stereochemical purity and batch-to-batch consistency. Certificates of Analysis (COA) with detailed specifications are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). 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, and open flames.
