Description

2-Methyl-4,5-Dihydrofurane-3-Thiol is a high-purity sulfur-containing heterocyclic compound, a key flavor and fragrance intermediate prized for its potent, meaty, and roasted character. Its value lies in its ability to impart savory, umami-like notes at very low concentrations, making it essential for creating authentic and complex flavor profiles. This compound is primarily needed by flavor and fragrance manufacturers, food technologists, and research laboratories developing products for the savory food, snack, and pet food industries.

Application

• Flavor & Fragrance Industry: A critical building block for creating savory, roasted, and meaty flavor profiles in processed meats, savory snacks, soups, sauces, and gravies.
• Food Technology: Used to enhance and authenticate the flavor of plant-based meat alternatives, providing the characteristic "cooked" or "grilled" meat notes.
• Pet Food Palatability: Incorporated into premium pet food and treat formulations to significantly improve aroma and taste acceptance.
• Research & Development: Serves as a reference standard and a key synthetic intermediate in organic chemistry and flavor science research.
• Seasoning Blends: Used in the development of complex seasoning mixes and reaction flavors for convenience foods.
• Functional Fragrances: Employed in trace amounts to add depth and character to certain fragrance compositions.
