Description

3-(Methylthio)-2-Butanone is a sulfur-containing ketone with a distinctive organoleptic profile. This compound is valued as a versatile intermediate and flavor/fragrance ingredient, offering unique organosulfur notes. It is primarily sought by manufacturers in the flavor & fragrance, agrochemical, and fine chemical synthesis industries for its reactive thioether functionality and sensory characteristics.

Application

• Flavor & Fragrance Ingredient: Used as a key component to impart savory, meaty, or roasted nuances in savory flavorings and specialty fragrance compositions.
• Chemical Intermediate: Serves as a crucial building block in the synthesis of more complex sulfur-containing molecules for pharmaceuticals and agrochemicals.
• Agrochemical Synthesis: Employed in the production of certain pesticides and herbicides where the methylthio group is integral to biological activity.
• Research & Development: Utilized in organic chemistry R&D for studying reactions of α-functionalized ketones and thioethers.

Quality Control

Our 3-(Methylthio)-2-Butanone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specifications such as assay (by GC), identity (IR), and specific gravity is provided to guarantee it meets the requirements for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in opened containers. Recommended storage temperature: 2-8°C.
