For Research and Development scientists and product formulators, a deep understanding of chemical properties is fundamental to innovation. Dimethylthiomethane (CAS 1618-26-4), a compound valued for its distinct aroma profile, possesses several key chemical characteristics that dictate its use in flavor applications and beyond.

Chemically known as Bis(methylthio)methane or 2,4-Dithiapentane, this molecule features a central methylene group (-CH2-) flanked by two methylthio groups (-SCH3). This structure, with the formula C3H8S2, contributes to its characteristic sulfurous odor, often described as pungent, garlic-like, and slightly green or spicy. The odor threshold is quite low, meaning even small concentrations can significantly impact a food product's aroma and taste.

The physical properties of Dimethylthiomethane are equally important for handling and formulation. It typically presents as a clear to pale yellow oily liquid. Key physical data includes a boiling point of approximately 147 °C and a density around 1.059 g/mL at 25 °C. Its refractive index is also a significant parameter, usually around 1.53. These properties inform storage conditions, mixing protocols, and compatibility with other ingredients.

In the context of food applications, the high purity of Dimethylthiomethane is paramount. Manufacturers often specify a purity of 99% or higher. This chemical is widely recognized under FEMA 3878 and is a registered flavor ingredient. Its utility lies in its ability to enhance savory notes, replicating the authentic taste of ingredients like mushrooms, truffles, and cooked meats. For anyone looking to buy Dimethylthiomethane for R&D purposes, it's crucial to specify the required purity and source from a reliable CAS 1618-26-4 chemical supplier.

When evaluating potential suppliers, ask about the manufacturing process and any quality assurance measures in place. A competent Dimethylthiomethane manufacturer in China will be able to provide detailed specifications and support. Understanding the market pricing for Bis(methylthio)methane will also aid in budget planning. For those needing smaller quantities for laboratory testing, inquire about sample availability. When considering bulk purchases, discuss pricing for Formaldehyde Dimethyl Mercaptal to ensure cost-efficiency.

The unique chemical structure and potent odor of Dimethylthiomethane make it a valuable tool for flavorists and chemists. By thoroughly understanding its properties and sourcing it from trusted vendors, R&D professionals can effectively harness its potential to create innovative and appealing food products.
