Quality Control

Our 9-cis-Beta,β-Carotene,Radicalion(1-) is produced and handled under stringent conditions to ensure research-grade purity and stability. Each batch is characterized using advanced spectroscopic techniques including UV-Vis, EPR (Electron Paramagnetic Resonance), and HPLC to confirm identity and assess purity. A comprehensive Certificate of Analysis (COA) detailing spectroscopic data and handling instructions is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon or nitrogen) at -20°C or below to minimize degradation. This material is easily oxidized and light-sensitive. Allow the sealed container to reach room temperature in a dark environment before opening to prevent condensation.
