Quality Control

Our (1S)-(+)-Thuj-3-Ene is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by GC or HPLC, to ensure it meets exacting specifications. A Certificate of Analysis (COA) detailing identity, purity, and specific rotation is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled room temperature (15-25°C). 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 preservation. Keep away from heat, sparks, and open flames.
