Quality Control

Our Brazilin is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, heavy metal limits, and residual solvent analysis, in line with industry best practices. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

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 light-sensitive and easily oxidized nature, prolonged exposure to light, air, or elevated temperatures should be avoided to maintain stability and potency. For long-term storage, consider an inert atmosphere.
