Quality Control

Our Potassium Indan-5-Sulphonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, impurity profile, and loss on drying. Our quality commitment supports applications requiring reliable and traceable raw materials for research and regulated industries.

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 sealed and protected from humidity. Keep away from incompatible materials.
