Quality Control

Our Potassium 3-Mercaptopropionate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with key parameters such as assay, impurity profile, and physical characteristics. Our quality commitment ensures the material meets the high standards required for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to handle under an inert atmosphere and minimize exposure to air and moisture for long-term stability.
