Quality Control

Our 2,3-Dimethyl-p-Phenylenediamine, 99 is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standard of 99% minimum assay and conforms to the specifications outlined in the technical data sheet. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available upon request to support your quality assurance protocols.

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 material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize degradation.
