Quality Control

Every batch of Propanedinitrile, (3-Oxobutyl)- is produced under a strict quality management system. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing 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, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials such as strong oxidizing agents.
