Quality Control

Our 2,4'-Diaminodiphenylmethane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. Certificates of Analysis (COA) documenting key parameters such as assay, melting point, and related substances are provided to guarantee batch-to-batch consistency and compliance with your technical requirements.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from strong oxidizing agents, acids, and moisture. For long-term storage, consider an inert atmosphere (nitrogen or argon) to maintain product integrity.
