Quality Control

Our Tamarixetin is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity, suitable for research and development applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry guidelines to support your regulatory and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
