Quality Control

We maintain strict quality control protocols for 2-Chloro-5-Methyl-1,4-Phenylenediamine to ensure batch-to-batch consistency and high purity. Our standard grade typically meets a specification of ≥98% purity (by HPLC). Each production lot is analyzed with modern analytical techniques, and a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is available upon request. We can also tailor specifications to meet specific customer requirements for research or industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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. Keep away from strong oxidizing agents, acids, and bases.
