Quality Control

Every batch of 1,2-Benzenediamine, 4-(1-Methylethyl)- is produced and tested under a strict quality management system to ensure consistency and reliability for industrial applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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 properties of being easily oxidized (store under inert atmosphere) and light-sensitive, it is recommended to handle under an inert atmosphere such as nitrogen and minimize exposure to air and light during use.
