Quality Control

Our 5,9,13-Trimethyl-1-Isopropyl-4,16-Dioxatricyclo[11.2.1.03,5]Hexadec-8-En-12-Ol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment, to ensure consistent organoleptic properties and chemical identity. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and purity.
