Quality Control

Our 4-(Ethylthio)Butyraldehyde is manufactured 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 to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated place at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and handled with appropriate precautions.
