Quality Control

Our 3,3'-Methylenebis(1,2-Benzenediamine) 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 standards for advanced material synthesis. A Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to guarantee traceability and consistency for your formulations.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents, acids, and moisture.
