Quality Control

Our n-Ethyl-5-Sulphoanthranilic Acid is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the high standards required for industrial and research applications. A detailed Certificate of Analysis (COA) documenting purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
