Quality Control

Our n-Ethyl-n-(3-Sulfopropyl)-m-Aminophenol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for structural identification, and loss on drying to monitor moisture content. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your technical requirements.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
