Quality Control

Our Methyl 3-Methyl-4-Oxobutanoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC/HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment and are available upon request.

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. Recommended storage temperature is 2-8°C for long-term stability. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
