Quality Control

Our production of Benzoic Acid, 2-Mercapto-, Methyl Ester, Sodium Salt adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet defined specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to guarantee traceability and compliance for your critical applications.

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 to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
