Quality Control

Our 5-Chloro-3-Methyl-1,2-Phenylenediamine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, residual solvent analysis, and identity confirmation via FT-IR and NMR spectroscopy. We provide Certificates of Analysis (COA) with each shipment, detailing all critical quality attributes to ensure compliance with your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled 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 preservation. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents.
