Quality Control

Our Potassium 2-Chloro-4-Sulphobenzoate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for synthetic intermediates. Certificates of Analysis (COA) are provided with every shipment, detailing all critical quality parameters. We adhere to cGMP principles where applicable to guarantee consistent purity and reliable performance in your processes.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
