Quality Control

Every batch of o-Ethylhydroxydihydrofusarubin is manufactured and tested under a strict quality management system to ensure identity, purity, and consistency. We provide comprehensive analytical documentation, including a Certificate of Analysis (COA) with detailed results from techniques such as HPLC, NMR, and mass spectrometry. Our quality commitment ensures the material is suitable for demanding applications in research and development.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to light and oxidation, prolonged exposure to air or light should be avoided to maintain stability and purity.
