Quality Control

Our α-Calacorene is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including GC, HPLC, and NMR, to verify identity and purity against established specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to light and tendency for oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
