Quality Control

Our n-Phenyl-N'-(2-Methylphenyl)-p-Phenylenediamine is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including assay, purity profiling, and physical property verification, to ensure it meets precise industry specifications for performance. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended. Keep away from strong oxidizing agents.
