Quality Control

Our 4-Ethyl-5-Methylthiazole is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC and GC-MS, to ensure identity, purity, and organoleptic consistency. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, confirming compliance with relevant flavor industry standards such as FEMA and FCC where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Keep away from heat, sparks, and open flame.
