Quality Control

Our (E)-2-Methyl-2-Butenenitrile is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP and ISO 9001 compliant manufacturing for applications requiring the highest level of quality assurance and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. Due to its unsaturated nature and nitrile group, it is recommended to store under an inert atmosphere for long-term stability and to minimize potential polymerization or degradation.
