Quality Control

Our Sodium 4-Hydroxy-6-(Methylamino)Naphthalene-2-Sulphonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets precise specifications for use as a high-grade intermediate. Certificates of Analysis (COA) documenting all quality parameters 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, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
