Quality Control

Our n-(3,4-Diaminophenyl)Methanesulfonamide is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive synthesis applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen) for long-term storage or after opening to maintain product integrity.
