Quality Control

Our Isovelleral is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including chromatographic purity assays and structural confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profiles to meet the stringent requirements of our global R&D and manufacturing clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 or argon) for long-term preservation. Keep away from heat, open flames, and incompatible materials.
