Quality Control

Our 8-Epixanthatin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR, MS). We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with research-grade and pharmaceutical intermediate specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) to prevent oxidation and degradation. The container should be kept in a cool, dry, and well-ventilated area, away from incompatible materials.
