Quality Control

Our 7,8-Dihydro-β,β-Carotene-3,3'-Diol is produced and tested under strict quality management systems. Each batch is analyzed to ensure it meets high-purity standards suitable for nutraceutical and research applications. Comprehensive testing includes identity confirmation, assay, and impurity profiling. A Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. The material is easily oxidized and light-sensitive; prolonged exposure to air, heat, or light should be avoided to maintain stability and potency.
