Quality Control

Our 2-(Methylthio)Propionic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets the high standards required for industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its acidic nature and sensitivity to oxidation, it is recommended to store under an inert atmosphere for long-term preservation. Recommended storage temperature: 2-8°C.
