Quality Control

Our (+)-Dihydrocarvone is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity and chemical assay, to ensure it meets the high standards required for flavor, fragrance, and synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, optical rotation, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 2-8°C or as specified on the label. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from heat, sparks, and open flame.
