Quality Control

Every batch of 2-[(p-Aminophenyl)Sulphonyl]Ethanol is manufactured under a strict quality management system. We ensure compliance with relevant industry standards through rigorous in-process and final release testing, which includes identity confirmation, purity assay, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and product integrity for your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product quality.
