Quality Control

Every batch of 9,10-Epoxy-7,8-Dihydroxy-7,8,9,10-Tetrahydro-5-Methylchrysene is manufactured and analyzed under strict quality management protocols to ensure identity, purity, and consistency. Our products undergo rigorous quality testing, including chromatographic purity analysis and spectroscopic identification, to ensure compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture uptake and thermal stress.
