Quality Control

Our (+)-trans-Nootkatol is produced and tested under strict quality management protocols. Each batch is analyzed to ensure high chemical purity and enantiomeric excess, meeting the stringent requirements of the flavor, fragrance, and research sectors. A comprehensive Certificate of Analysis (COA) detailing identity, purity (by GC/HPLC), and specific rotation is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This compound is easily oxidized; for long-term storage, keeping the container under an inert atmosphere (e.g., nitrogen or argon) is recommended to maintain optimal stability and purity.
