Quality Control

Our 3(Or 4)-Methylbenzene-1,2-Diamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for industrial and research applications. A Certificate of Analysis (COA) detailing specific batch results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), it is recommended to keep the container under an inert gas blanket (e.g., nitrogen or argon) after opening to maximize shelf-life and maintain product integrity.
