Quality Control

Every batch of Juncuenin B is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency, supporting compliance with research and development standards. A detailed Certificate of Analysis (COA) with supporting chromatographic and spectroscopic data (e.g., HPLC, NMR) is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
