Quality Control

Our Sodium Hydrogen (4-Methylsulphonatophenoxy)Acetate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting results for assay, related substances, and other critical parameters is provided with each shipment to guarantee traceability and compliance.

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 tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
