Quality Control

Our Sodium 6,7-Bis[(Phenylsulphonyl)Oxy]Naphthalene-2-Sulphonate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, related substances, and other critical parameters are available upon request. We adhere to cGMP principles where applicable to support its use in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
