Quality Control

Our 4A,8A-Dihydronaphthalene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and GC-MS for identity confirmation, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, containers should be kept sealed and purged after each use to maintain product integrity.
