Quality Control

Our 3,8-p-Menthadiene is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by GC), optical rotation, and refractive index are provided and available upon request to support your quality assurance protocols.

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 integrity. Recommended storage temperature is 2-8°C (36-46°F) for extended stability.
