Quality Control

Our Propanedinitrile, [(3,4-Dihydroxy-5-Methylphenyl)Methylene]- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can support development projects with custom purity grades and analytical method development upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive (store away from light), it is recommended to handle under an inert atmosphere such as nitrogen or argon for long-term storage and to minimize exposure to air and light during use.
