Quality Control

Our Gossypol-Polyvinylpyrrolidone is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with key parameters such as complex composition, gossypol content, and residual solvents. Our quality commitment supports its use in research and development applications where reliable material characteristics are paramount.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be sealed under an inert gas (e.g., nitrogen or argon) after opening and kept in a desiccator to minimize exposure to moisture and air.
