Quality Control

Every batch of 9-Methoxy-4,5-Dihydroxy-4,5-Dihydrobenzo(A)Pyrene is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, MS), to ensure compliance with exacting research-grade standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical applications.

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) in a cool, dry, and well-ventilated place. Due to its sensitivity to light and oxidation, prolonged exposure to air or light should be avoided to maintain product integrity.
