Quality Control

Our 3,5-Dimethyl-1,2-Phenylenediamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure it meets the highest standards of purity and consistency. Certificates of Analysis (COA) are provided with every shipment, detailing all specified parameters 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 room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
