Quality Control

Our Sodium 3-Mercapto-2-Butanolate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay and impurity profiling, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and air. Recommended long-term storage temperature is 2-8°C.
