Quality Control

Our 2'-(Dibenzylamino)-6'-(Diethylamino)Fluoran is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive chromogenic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and performance reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen) for long-term storage or when opening the primary container to maximize shelf-life and maintain product integrity.
