Quality Control

Our production of Benzonitrile, 3-Ethyl-4-Formyl- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with your research or manufacturing standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
