Quality Control

Every batch of 8,9-Dimethylbenz[A]Anthracene 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, to ensure compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment and is available upon request.

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, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from heat and incompatible materials.
