Quality Control

Our 2,4-Diaminophenol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for industrial and research use. Certificates of Analysis (COA) documenting purity, appearance, and other critical parameters are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, prolonged exposure to air and light should be avoided. For long-term storage, consider an inert atmosphere.
