Quality Control

Our 5-Acetamido-3-Amino-2-Hydroxybenzenesulphonic Acid is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling. Certificates of Analysis (COA) documenting all test results are provided and can be tailored to meet specific customer or regulatory requirements. We are committed to supporting our clients' needs for GMP and ISO-aligned quality standards.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product stability and performance. Keep away from incompatible materials such as strong bases and oxidizing agents.
