General description
Bis(methylthio)methane, a volatile sulfur compound, is the key component of white truffle aroma. It is also reported to be an off-flavor in crustaceans such as prawn and sand lobster.
Natural occurrence: Truffles cheese, shittake mushrooms, and lobster.
Application
- RIFM fragrance ingredient safety assessment, bis-(methylthio)methane, CAS Registry Number 1618-26-4.: This safety assessment explores the use of bis(methylthio)methane as a fragrance ingredient. The study evaluates its toxicological profile, confirming its safety for use in various cosmetic and personal care products (Api et al., 2021).
- Characterization of the Key Aroma Compounds in Three Truffle Varieties from China by Flavoromics Approach.: Bis(methylthio)methane is identified as a significant aroma compound in Chinese truffle varieties. The research uses a flavoromics approach to map out the aroma profiles, supporting the enhancement of truffle-based products (Feng et al., 2019).
- Multidimensional Gas Chromatography Coupled to Combustion-Isotope Ratio Mass Spectrometry/Quadrupole MS with a Low-Bleed Ionic Liquid Secondary Column for the Authentication of Truffles and Products Containing Truffle.: This analytical method leverages bis(methylthio)methane as a marker for authenticating truffle products. The study improves the reliability of truffle product verification, ensuring quality control in the food industry (Sciarrone et al., 2018).
- Olfactometry Profiles and Quantitation of Volatile Sulfur Compounds of Swiss Tilsit Cheeses.: Bis(methylthio)methane is quantified as a key sulfur compound in Swiss Tilsit cheese. The study′s findings contribute to the understanding of cheese aroma profiles, aiding in the development of flavor-enhanced dairy products (Fuchsmann et al., 2015).

Tyrosinase is an enzyme having two copper atoms at the reactive site occurring in prokaryotic and eukaryotic organisms. In animals tyrosinase is responsible for pigmentation, in plants for protection of injured tissues or, as in fungi, to harden cell walls.

Two topologically comparable complexes, [Ag6(CF3CO2)3(L1-Me)3(SCH3)3]infinity (1) and [Ag6(CF3CF2CO2)3(L1-Me)2(SCH3)3(H2O)]infinity (2), were prepared and characterized by single-crystal diffractometry. The structures consist of Ag12S6 clusters linked by bis(methylthio)methane ligands, L1-Me, thus forming 1D coordination polymers. The 12 Ag atoms of the cluster are
