4-(Methylthio)butanol is primarily used in the flavor and fragrance industry due to its unique sulfur-containing structure, which imparts a distinct aroma. It is often employed as a key ingredient in creating savory, meaty, or roasted flavors, making it valuable in the formulation of food products such as soups, sauces, and processed meats. Additionally, its odor profile is utilized in perfumery to add depth and complexity to certain fragrances, particularly those aiming for a warm or earthy character. The compound’s versatility in enhancing sensory experiences makes it a significant component in both culinary and cosmetic applications.
