Chemical Structure

Basic Info
4-Methylthio-2-butanone (4-Methylthio-2-butanone) is an organosulfur compound with the chemical formula C5H10OS. It is a volatile liquid with a strong odor, usually presenting a foul sulfur-like odor, and is often used as a flavor additive in the food and flavor industry. Its molecule contains a methylthio (-SCH3) and a keto (C=O) structure, which gives it unique chemical reactivity and aromatic properties. The synthesis of 4-methylthio-2-butanone is usually carried out by a sulfurization reaction to introduce a methylsulfane group into the butanone molecule to form this unique chemical.
4-Methylthio-2-butanone can be used as a pharmaceutical synthesis intermediate. In the case of iNOS compound 29, iNOS plays a major role in the formation of ROS under oxidative conditions. However, excessive NO production by iNOS has been associated with several pathological conditions, including ischemia/reperfusion injuries, septic-shock, vascular dysfunction and rejection in diabetes.

Product Packaging
1.Food flavor additives:
The main application of 4-methylthio-2-butanone in the food industry is as a flavor additive, especially in simulating the flavor of specific foods. It is used as a flavor enhancer and to imitate the taste of meat, dairy products, sausages, and other processed food. It can be used in dairy products to simulate a mature taste similar to butter or cheese, while it is also commonly used in meat products to give them a “burnt”, “charred”, or “burnt-out” flavor. It is effective at improving the flavor of food in low concentrations. This chemical can be used in processed foods, to enhance natural flavors through cooking and smoking. It is important to carefully control the dosage due to the strong aroma.
2.Flavors, fragrances and the industry:
In flavor and fragrance products, 4-methylthio-2-butanone is used to give products a unique and deep aroma. The sulfur-like smell of 4-methylthio-2-butanone makes it an ideal ingredient for perfumes and fragrances. It can be mixed with other flavors such as wood smoke leather, or oriental notes, to increase the complexity and layers of aroma. Its unique scent is ideal for the creation of perfumes that have a “mature”, “unique” or “unique style” or to enhance base fragrances. In personal care products such as soap, shampoo or shower gel, 4-methylthio-2-butanone can also be used as a flavoring agent to create special fragrance effects. Its primary function is to increase the uniqueness and longevity of the overall scent. It can also work with other natural or artificial fragrances to create a more complex and diverse fragrance experience.
3.Special odor adjustment in cosmetics:
In the cosmetics industry, 4-methylthio-2-butanone is often used in some specific types of cosmetics and skin care products, especially high-end, personalized and customized products. It is used in these products as a raw material for fragrance to give cosmetics an unique smell. For example, in some skin creams, facial masks, and fragrance products that emphasize “natural” or “retro” styles, 4-methylthio-2-butanone can bring a complex, mature, and even somewhat mysterious scent, giving consumers a unique olfactory enjoyment. Cosmetics use a very small amount of 4-methylthio-2-butanone, which is used to enhance the aroma of other fragrances and give the product a strong sense of smell. Due to its strong sulfur smell, 4-methylthio-2-butanone needs to be used in a precise ratio to avoid its odor being too prominent and affecting the final product aroma.
