Quality Control

Our Pyrazine, 3,5-Dimethyl-2-(2-Methylbutyl)- (9Ci) is produced and tested under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

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