Reactivity Profile
THIAZOLE, An organosulfide amine derivative. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.

OccurrenceReported 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.
UsesThiazoles were used to create novel recognition motifs for interaction with divalent and trivalent metal ions in siderophores or antibiotics.
UsesThiazole 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 Grignards 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.
UsesOrganic synthesis of fungicides, dyes, and rubber accelerators.
Colorless or pale yellow liquid with a foul odor.
