Quality Control

Our (1S,8Aα)-Decahydro-1,4Aβ-Dimethyl-7β-(1-Methylethyl)Naphthalene is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets stringent purity and identity specifications, with testing typically including GC, GC-MS, and optical rotation. Certificates of Analysis (COA) documenting full specifications are available for every shipment upon request.

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 potential concentration changes. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
