Bis(2-methyl-3-furyl) Disulfide CAS 28588-75-2 | FEMA 3259 | Flavor & Fragrance

Bis(2-methyl-3-furyl) Disulfide, accurately identified by its CAS registry number 28588-75-2 and commonly referred to under synonyms such as Bis(2-methyl-3-furyl) disulphide, is a high-impact organosulfur compound widely utilized in flavor and fragrance applications. Its safety and suitability for use in consumables are formally recognized through its FEMA (Flavor and Extract Manufacturers Association) number 3259, which designates it as an approved flavoring substance. This compound is characterized by its potent aroma profile, typically described as meaty, savory, roasted, and sulfurous, making it an essential ingredient for advanced flavor and fragrance development.

In the flavor industry, Bis(2-methyl-3-furyl) Disulfide serves as a critical flavor compound and flavor enhancer. It is extensively employed in the formulation of savory and umami-rich food flavorings, especially for replicating and intensifying meat-like, roasted, and cooked notes. Key applications include processed meat products, savory snacks, ready-to-eat meals, sauces, soups, and meat analog (plant-based protein) formulations. Its efficacy at very low concentrations allows flavorists to achieve authentic and robust flavor profiles with significant impact. Within the fragrance industry, this compound is valued as a powerful aroma chemical and fragrance ingredient. Perfumers leverage its distinctive sulfurous and roasted character to introduce unique savory, gourmet, or earthy nuances into fine fragrances, personal care products, and home fragrance systems, enhancing complexity and depth in scent compositions.

From a technical standpoint, Bis(2-methyl-3-furyl) Disulfide also functions as a specialized chemical intermediate in organic synthesis. Research and development laboratories utilize it as a building block for synthesizing more complex sulfur-containing molecules, which may find applications in advanced material science or the creation of novel aroma compounds. Its FEMA GRAS (Generally Recognized As Safe) status, linked to FEMA 3259, is crucial for its global use in food-grade and compliant applications. Manufacturers and flavor houses seeking this material prioritize sourcing high-purity Bis(2-methyl-3-furyl) Disulfide from reliable suppliers capable of providing consistent quality, comprehensive technical data sheets, safety documentation, and regulatory support to ensure seamless integration into final products.
