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.

使用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 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.
一般的な説明Colorless or pale yellow liquid with a foul odor.
使用用途チアゾールの主な使用用途は有機合成原料です。 チアゾール環においては2位が求核的、5位が求電子的サイトとして反応します。チアゾールに対してグリニャール試薬やアルキルリチウムなどを作用させると2位の水素が引き抜かれ、メタル化されます。また、2-クロロチアゾールに対してアミンなどの求核剤を作用させると置換反応が起きます。 チアゾールの誘導体には、工業薬品 (加硫促進剤) 、殺菌剤、駆虫剤、医薬品、染料などがあり、重要なものが多いです。加硫とは、原料ゴムに高い弾性を与えるため、硫黄によってゴムの分子同士を結合させることを言いますが、通常は長時間を必要とするため加硫促進剤を添加します。チアゾール系の加硫促進剤はゴムを汚染しないので、透明物や色物に好適です。また、様々なジエン系ゴムにも使用されています。 チアゾールの殺菌剤としての利用について、チアゾールは微生物に薬理的に作用するため、直接微生物に接触、吸収されて初めて作用を示します。そのため、使用用途は化粧品の防腐剤、農薬、洗浄剤として、液状あるいはエマルジョンの状態の製品に使用されています。 チアゾール構造を含む医薬品は主に、抗生物質のセフビロム、抗がん剤のブレオマイシン、チアミン (ビタミンB1) です。無機酸、 (Ⅱ) と安定な錯体を形成するため、さまざまな形で販売されています。

Liquid
Colourless to pale yellow liquid; green, sweet, nutty, tomatoe note
化学的特性Thiazole has a green, sweet, nutty, tomato note.
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)
定義thiazole: A heterocyclic compound containing a five-membered ringwith sulphur and nitrogen heteroatoms, C3SNH3. A range of thiazoledyes are manufactured containingthis ring system.
