Quality Control

Our 2-[(Methylthio)Methyl]-2-Butenal is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for identity, purity, and olfactory profile, consistent with the requirements of the flavor and fragrance industry. Certificates of Analysis (COA) documenting purity (typically by GC), identity (IR), and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at controlled room temperature (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 maximize shelf life and maintain product integrity. Keep away from heat, sparks, and open flame.
