Quality Control

Our 9,9-Dimethyl-9H-Fluorene-2,7-Diamine is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency suitable for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to light and oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
