Quality Control

Our sec-Butyl 3-Methylbut-2-Enoate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation (IR), to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
