Benzothiazole
Benzothiazole is an aromatic heterocyclic compound with the chemical formula C 7 H 5 NS. It is colorless, slightly viscous liquid. Although the parent compound, benzothiazole is not widely used, many of its derivatives are found in commercial products or in nature. Firefly luciferin can be considered a derivative of benzothiazole.

Green carbon disulfide surrogate via a combination
An efficient and green carbon disulfide surrogate via facile combination of potassium sulfide and chloroform has been developed. A variety of benzothiazine-thiones and benzothiazole-thiones were straightforwardly established along with the formation of five new chemical bonds in one pot from readily available starting materials, in which the widely used 2-mercaptobenzothiazole (MBT) was ...

Novel synthesis of benzothiazole by self-redox ... - DeepDyve
1 Introduction Organosulfur compounds are widely observed in natural products and used as drugs. 1 The synthesis of organosulfur compounds has received broad attention in recent years, with various methods developed to construct the C–S bonds. 2 Sulfur, metal sulfides, thiols, and other sulfur reagents have been widely used as sulfur-introducing reagents to prepare organic sulfur-containing molecules. 3 However, most thiols, especially aryl thiols, are readily oxidized to form disulfide. 4 ...

acceleratorsand acceleratorsystems
Raw materials for thiazoles are aniline, carbon disulfide, and sulfur. The chief thiazole accelerators are 2-mercaptobenzothiazole (MBT), benzoth-iazole disulfide (MBTS), and the zinc salt of 2-mercaptobenzothiazole. The zinc salt is rarely used in dry compounding but is used more in latex foams and dipped goods. Both MBT and MBTS can cause scorching
