Quality Control

Every batch of (19S,23S)-5β,19-Epoxy-19,23-Dimethoxycucurbita-6,24-Dien-3β-Ol is produced and controlled under a strict quality management system. We employ advanced analytical techniques including HPLC, GC-MS, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with each shipment to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
