Quality Control

Every batch of our (2S)-flavanone derivative is manufactured under strict quality management systems. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with detailed results from HPLC, chiral analysis, and NMR spectroscopy to verify identity, purity, and enantiomeric excess. Our quality assurance protocols are designed to meet the stringent requirements of research and pre-clinical development.

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.
