| Benzothiazole is a colorless, slightly viscous liquid with a melting point of 2°C, and a boiling point of 227-228°C. The density of benzothiazole is 1.644 g/ml an heterocyclic organic compound. Benzothiazole has no household use. It is used in industry and research. The degree Celsius (°C) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701–1744), who first proposed a similar system in 1742. ...

Link titleAn organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with exception of carbides, carbonates and carbon oxides. ...
Chemistry
Being a heterocyclic compound, benzothiazole finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive handles which allow for functionalization. In chemistry, an aromatic molecule is one in which electrons are free to cycle around circular arrangements of atoms, which are alternately singly and doubly bonded to one another. ...
Many dyes, such as thioflavin have benzothiazoles as a structural motif.
