Quality Control

Our Pyrazine, 3-Ethyl-2-Methyl-5-(1-Methylethyl)- (9Ci) is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
