Description

Furan-2-Yl-Methanethiol CAS NO 175236-33-6 is a high-purity sulfur-containing heterocyclic compound characterized by its distinctive, potent aroma. This organosulfur compound is a key flavor and fragrance intermediate, prized for its ability to impart roasted, coffee-like, and meaty notes at extremely low concentrations. It is an essential building block for flavorists and fragrance chemists in the food, beverage, and perfumery industries, as well as for researchers in synthetic organic chemistry and material science.

Application

• Flavor & Fragrance Industry: A critical ingredient for creating and enhancing savory, roasted, and meaty flavor profiles in processed foods, snacks, sauces, and savory flavorings.
• Beverage Formulation: Used to impart or modify coffee, cocoa, and nutty notes in coffee flavors, alcoholic beverages, and specialty drinks.
• Perfumery & Aromachemicals: Serves as a powerful base note or modifier in fine fragrances and functional perfumes to add depth and complex roasted nuances.
• Synthetic Organic Chemistry: Acts as a versatile building block or ligand precursor in the synthesis of more complex heterocyclic compounds and pharmaceuticals.
• Research & Development: Utilized in academic and industrial R&D for studying organosulfur chemistry, reaction mechanisms, and sensory science.
• Standards & Reference Materials: Supplied as a certified reference standard for analytical testing, quality control, and regulatory compliance in flavor and food safety labs.

Quality Control

Our Furan-2-Yl-Methanethiol is produced and handled under strict quality management protocols. Each batch is analyzed using advanced techniques including GC, GC-MS, and NMR to ensure identity, purity, and olfactory profile consistency. We provide comprehensive Certificates of Analysis (COA) detailing all specifications, and our quality systems support compliance with relevant standards for flavor and fragrance ingredients, including FCC and FEMA GRAS where applicable.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this product should be stored under an inert atmosphere (nitrogen or argon) at 2-8°C. For long-term storage, keep the sealed container in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Allow the container to reach ambient temperature before opening to minimize moisture ingress and oxidation.
