General description

4-Methyl-5-vinylthiazole is a sulfur-containing volatile compound identified in garlic, pork and mature whiskey. It is also present in the floral scent of a few species of genus Annonaceae and Araceae, where they play a major role in attracting the scarab beetle pollinators.

Application

  • Safety and efficacy of the feed additive 4-methyl-5-vinylthiazole [15.018] belonging to chemical group 29 for all animal species (FEFANA asbl): This study evaluates the safety and efficacy of 4-Methyl-5-vinylthiazole as a feed additive, showcasing its applications in veterinary nutrition and its potential as a chemical intermediate in various industrial applications (EFSA Panel, 2023).

  • Study on the influences of two thiazole flavor ingredients on Cu corrosion caused by chloride ion: This paper explores the effects of thiazole compounds, including 4-Methyl-5-vinylthiazole, on metal corrosion, providing insight into its potential uses in materials science and its role as an organic synthesis intermediate in creating corrosion inhibitors (Mo et al., 2017).
