Quality Control

Our production of 2-[(7-Amino-1-Naphthyl)Sulphonyl]Ethanol adheres to stringent in-process controls and final batch testing to ensure consistent purity and performance. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We support compliance with global regulatory frameworks, and specifications can be aligned with customer-specific requirements for research or cGMP manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product stability and handling properties.
