Quality Control

Our 2,5-Dimethylfuran-3-Thiol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC and/or HPLC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting compliance with relevant flavor and fragrance industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace and avoid prolonged exposure to air.
