Descrição geral

Trimethylsulfonium hydroxide (TMSH) is a methylating reagent. It can be prepared by dissolving trimethylsulfonium iodide in methanol and water solvent further treating with silver oxide.

Aplicação

TMSH solution has been used as a derivatizing agent in a study to determine the fatty acids in milk samples using thermochemolysis-gas chromatography-mass spectrometry.

Trophic interactions are a fundamental aspect of ecosystem functioning, but often difficult to observe directly. Several indirect techniques, such as fatty acid analysis, were developed to assess these interactions. Fatty acid profiles may indicate dietary differences, while individual fatty acids
