Quality Control

Our 2-Ethyl-4-(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)-2-Butenal is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, IR, and NMR, to ensure identity, purity, and olfactory profile consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to guarantee compliance with your quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is easily oxidized; for long-term storage, an inert atmosphere (nitrogen blanket) is recommended to maintain optimal stability and prevent degradation.
