Quality Control

Our 3,5,6-Dimethyl-2-Isobutylpyrazine is produced under strict quality management systems. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and olfactory profile. Certificates of Analysis (COA) documenting key parameters such as assay (by GC), specific gravity, refractive index, and organoleptic properties are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, keep containers tightly sealed when not in use and away from heat and open flame.
