Quality Control

Our S-Furfuryl 2-Methylpropanethioate is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and/or HPLC analysis, to ensure high purity and consistent organoleptic performance. Certificates of Analysis (COA) detailing identity, purity, and specific impurity profiles are provided with each shipment. We adhere to relevant industry standards for flavor ingredient manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain stability and prevent degradation. Keep away from heat, sparks, and open flames.
