Benzothiazole Usage And Synthesis
DescriptionBenzothiazole and its derivative are recognized as the most important heterocyclic compounds. This series of compounds is of particular interests. It has various kinds of pharmacological properties and has been included in many kinds of natural products and pharmaceutical agents. The broad spectrum of pharmacological activity in individual benzothiazole derivative enables it to serve as unique and valuable scaffolds for experimental drug design. It is already known that benzothiazole and its derivative has various biological applications including anticancer, antimicrobial, anticonvulsant, antiviral, antidiabetic, antipsychotic, antiinflammatory, analgesic, fungicidal and diuretic. Its derivatives also have many applications in polymer chemistry, dyes, drugs, and silver photography as well as rubber industry.
Chemical Propertiesyellow liquid with an unpleasant odour
Chemical PropertiesBenzothiazole has a delicate, persistent, rose-like odor similar to that of quinoline.
OccurrenceReported found in apricot, cooked asparagus, mozzarella cheese, skim milk powder, roasted beef, beer, malt whiskey, coconut meat, fresh mango, cooked broccoli and kelp.
UsesIn organic synthesis.
UsesVarious benzothiazole-benzamides synthesized were evaluated for their analgesic and antidepressant activities.
DefinitionChEBI: An organic heterobicyclic compound that is a fusion product between benzene and thiazole. The parent of the class of benzothiazoles.
PreparationBy refluxing a mixture of zinc o-aminophenylsulfide and formic acid, followed by steam distillation of the alkalized reaction mixture; by heating formanilid or dimethylaniline with sulfur; by oxidation of 2-mercaptobenzothiazole or of the corresponding disulfide.
Aroma threshold valuesDetection: 80 to 450 ppb
Taste threshold valuesTaste characteristics at 3 ppm: meaty, vegetative, brown, cooked, beefy and coffee-like.
HazardHighly toxic by ingestion.
Safety ProfilePoison by ingestion,intraperitoneal, intravenous, and possibly other routes.When heated to decomposition it emits very toxic fumesof SOx, CN??, and NOx.
