Quality Control

Our Mes Sodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for life science and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing parameters such as assay, pH, endotoxin levels, and bioburden, where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 purity and stability.
