Quality Control

Every batch of 4-[(4-Aminophenyl)Methylsulfonylmethyl]Aniline is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards, and comprehensive analytical testing is performed to verify identity, purity, and impurity profiles. A Certificate of Analysis (COA) detailing specific results for each lot is provided to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
