Quality Control

Our Benzene Sulfonic Acid 2-(p-Acetamidoanilino)-5-A is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its nature as a strong acid/organic solvent, ensure containers are kept upright and sealed to prevent moisture absorption and degradation.
