Description

Furfuryl Mercaptan CAS NO 19980-20-2 is a sulfur-containing heterocyclic compound characterized by its distinctive, powerful aroma. This organosulfur chemical is a critical flavor and fragrance intermediate, prized for its ability to impart roasted, coffee-like, and meaty notes. It is an essential raw material for flavorists and perfumers in the food, beverage, and fragrance industries, as well as a valuable building block in organic synthesis for agrochemicals and pharmaceuticals.

Application

• Flavor & Fragrance Industry: A key ingredient for creating savory, roasted, and coffee flavors in processed foods, snacks, and beverages. Also used in perfume compositions for smoky or exotic notes.
• Food Additive Manufacturing: Serves as a precursor in the synthesis of more complex flavoring agents and reaction flavors (e.g., meat flavorings).
• Agrochemical Synthesis: Utilized as an intermediate in the production of certain pesticides and fungicides due to its reactive thiol and furan groups.
• Pharmaceutical Intermediates: Acts as a building block in the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Organic Synthesis & Research: Employed in laboratories as a reagent for introducing the furfurylthio moiety into target molecules.
• Specialty Chemicals: Used in the formulation of specialty catalysts and as a corrosion inhibitor in specific industrial processes.

Quality Control

Our Furfuryl Mercaptan is produced and tested under strict quality management systems. We offer various grades, including Food Grade (FEMA 2493, FCC) and high-purity synthesis grades, to meet diverse application needs. Each batch is analyzed via GC, GC-MS, and IR to ensure identity, purity, and organoleptic profile consistency. A comprehensive Certificate of Analysis (COA) detailing assay, specific gravity, refractive index, and organoleptic properties is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress. Recommended storage temperature: 2-8°C (refrigerated) for optimal stability.
