Quality Control

Our n-Methyl-4,4'-Methylenedianiline is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay and impurity profile determination by HPLC, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are available upon request.

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 and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability and purity. Keep away from strong oxidizing agents.
