Quality Control

Our Propanoic Acid, 3-Mercapto-2-Oxo- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, appearance, and specific impurities.

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). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents and bases.
