Description

3-((2-Methyl-3-Furyl)Thio)-2-Butanone is a high-purity sulfur-containing flavor and fragrance compound. This specialty chemical is valued for its unique organoleptic properties, imparting savory, meaty, and roasted notes to complex flavor formulations. It is a critical ingredient for flavorists and fragrance chemists in the food & beverage, savory flavorings, and fine fragrance industries seeking to create authentic and sophisticated sensory profiles.

Application

• Savory Flavor Creation: A key component in the formulation of meat, poultry, seafood, and savory snack flavors, providing authentic roasted and cooked character.
• Process Flavor Enhancer: Used in reaction flavors (e.g., Maillard reaction systems) to develop deep, complex meaty and umami notes.
• Fine Fragrance & Perfumery: Employed as a specialty base note to add unique roasted, sulfurous, or gourmand accents to high-end fragrance compositions.
• Food Seasoning & Bouillon: Incorporated into dry seasoning blends, soup bases, and bouillon cubes to enhance overall flavor depth and mouthfeel.
• Functional Food & Beverage: Used in protein-fortified drinks, nutritional bars, and plant-based meat alternatives to improve palatability and mask off-notes.
• Flavor Modifier & Potentiator: Acts as a flavor modifier to round out and potentiate other flavor ingredients in complex systems.

Quality Control

Our 3-((2-Methyl-3-Furyl)Thio)-2-Butanone is produced and tested to meet the stringent requirements of the flavor and fragrance industry. Quality is assured through rigorous analytical controls including GC, HPLC, and organoleptic evaluation. We provide full traceability and Certificates of Analysis (COA) for every batch, confirming identity, purity, and compliance with relevant standards such as FEMA GRAS and FCC where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider filling the headspace with an inert gas (e.g., nitrogen or argon). Keep away from heat, sparks, and open flame.
