Quality Control

Our 2-Keto-3-Butynoic Acid is produced and tested under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR for structural confirmation, and titration for assay determination to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from incompatible materials such as bases, oxidizing agents, and amines. Handle and store under an inert atmosphere (e.g., nitrogen) to minimize degradation.
