Quality Control

Our production of 4-(4-Aminophenyl)Sulfonyl-3-Methyl-n-Propyl-Aniline adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and KF titration for moisture content. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your specific research or production requirements.

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) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation.
