Chemische Eigenschaften
Thiazole has a green, sweet, nutty, tomato note.
Chemische Eigenschaften
colourless or pale yellow liquid with a disgusting smell
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.
Verwenden
Thiazoles were used to create novel recognition motifs for interaction with divalent and trivalent metal ions in siderophores or antibiotics.
Verwenden
Organic synthesis of fungicides, dyes, and rubber accelerators.
Verwenden
Thiazole is used as a flavoring agent and in the preparation of dyes and rubber accelerators. It serves as a component of the vitamin thiamine (B1). It acts as a protected formyl group used in natural product synthesis. It reacts with alkyl lithium and Grignard?s reagent to prepare organometallic complexes. It is involved in the electrophilic aromatic substitution and nucleophilic aromatic substitution at C-5 and C-2 positions respectively. Further, it undergoes alkylation reaction to get thiazolium cation, which is used as a catalyst in the Stetter reaction and the Benzoin condensation. In addition to this, it is involved in the preparation of alagebrium.
Definition
thiazole: A heterocyclic compound containing a five-membered ringwith sulphur and nitrogen heteroatoms, C₃SNH₃. A range of thiazoledyes are manufactured containingthis ring system.
Definition
A colorless volatile liquid, a beterocyclic compound with a five-membered ring containing three carbon atoms, one nitrogen atom, and one sulfur atom. It resembles PYRIDINE in its reactions.
Aroma threshold values
Detection: 3.1 ppm
Allgemeine Beschreibung
Colorless or pale yellow liquid with a foul odor.
Air & Water Reaktionen
Slightly water soluble.
Reaktivität anzeigen
Thioisocyanates, such as Thiazole, 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.
