Quality Control

Our trans-2-Pentenal is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC and HPLC analysis, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated area away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, the container must be kept tightly sealed and opened only under controlled conditions. Recommended storage temperature is 2-8°C for long-term stability.
