Quality Control

Our 3-Oxo-α-Ionol is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated flavor and fragrance applications.

Storage

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