Quality Control

Our production of this high-value phytochemical adheres to stringent quality protocols. Every batch is characterized using advanced analytical techniques including HPLC-DAD/MS for identity and purity confirmation and is supported by a comprehensive Certificate of Analysis (COA). We ensure compliance with relevant standards for analytical and research-grade materials. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent absorption of moisture. For long-term storage, consider desiccated conditions.
