Quality Control

Our Disodium n-[(p-Tolyl)Sulphonyl]-L-Glutamate is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for use in sensitive applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
