Quality Control

Our β-Selinene is produced and tested under strict quality management protocols to ensure consistency and purity for industrial applications. While specific grades can be tailored, our standard quality control includes verification of identity, purity by GC, and organoleptic properties. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment to guarantee supply reliability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product quality. Recommended storage temperature: 2-8°C (refrigerated) for long-term stability.
