Benzothiazole

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 1.238 g/ml (25 °C). It is a heterocyclic organic compound. Benzothiazole has no household use. It is used in industry and research.

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 sites which allow for functionalization.

Many dyes, such as thioflavin, and pharmaceutical drugs, such as riluzole, have benzothiazoles as a structural motif.
