Использование
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.
Определение
thiazole: A heterocyclic compound containing a five-membered ringwith sulphur and nitrogen heteroatoms, C3SNH3. A range of thiazoledyes are manufactured containingthis ring system.
Общее описание
Colorless or pale yellow liquid with a foul odor.
Реакции воздуха и воды
Slightly water soluble.
Профиль реактивности
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.
