Quality Control

Our Diethyl (2-Pentyl)Malonate, 98 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the specified 98% minimum purity and consistent performance. Certificates of Analysis (COA) with detailed batch-specific results are available upon request to support your quality assurance and regulatory needs.

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 acids, bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and volatilization.
