Quality Control

Our Sodium 3-Amino-4-Hydroxy-5-Nitrobenzenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with every shipment to guarantee 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
