Quality Control

Our Trilithium 5-Sulphonatoisophthalate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and confirmation of key physical-chemical parameters, to ensure consistency and compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, heavy metals, moisture content, and other relevant specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep away from incompatible materials such as strong acids.
