General Description
Colorless or pale yellow liquid with a foul odor.
Reactivity Profile
Thioisocyanates, such as THIAZOLE(288-47-1), are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat.
Air & Water Reactions
Slightly water soluble.
Chemical Properties
colourless or pale yellow liquid with a disgusting smell
Chemical Properties
Thiazole has a green, sweet, nutty, tomato note.
Occurrence
Reported found in roasted chicken, chicken fat, boiled and cooked beef, grilled and roasted beef, pork liver, beer, cognac and other types of grape brandy, rum, coffee, roasted barley, roasted filbert, roasted peanut, soybean, popcorn, oat products, rice bran, buckwheat, malt, wort, dried bonito, crab, crayfish, Chinese quince and other natural sources.
Application
The generation of thiazole derivatives by means of condensation of α-haloketones and thioamidesis referred to as the Hantzsch thiazole synthesis. This reaction takes place due to the strong nucleophilicity of the sulfur atom in thioamides or thioureas, and gives fantabulous yields for simple thiazoles but low yields for some substituted thiazoles, as of dehalogenation. It is a multistep reaction, and the intermediates have been isolated at low temperatures. This reaction has been changed to reduce the epimerization upon the formation of thiazole. Additionally, α-tosyloxy ketones have been used to replace α-haloketones for such reactions. It has wide application in the preparation of thiazole derivatives.
