1,2-Benzisothiazol-3(2H)-one Usage And Synthesis

Description	BIT (1,2-Benzisothiazol-3(2H)-one) is an irritant and also a skin sensitizer. Occupational allergie contact dermatitis has been reported mainly related to the use of cutting oils and greases in paint manufacturers, pottery mouldmakers, acrylic emulsion manufacturers, plumbers, printers and lithoprinters, paper makers, an analyticallaboratory, a rubber factory, and in employees manufacturing air fresheners.
Chemical Properties	Yellow Powder
Uses	Antimicrobial agent.
Uses	Isothiazolinone BIT is widely used in industry as a preservative in water-based solutions, such as pastes, paints and cutting oils. It exists at different concentrations in the different Proxel AB, GXL, CRL, XL2, XL, HL, TN, and in Mergal K-10.
Definition	ChEBI: Benzo[d]isothiazol-3-one is an organic heterobicyclic compound based on a fused 1,2-thiazole and benzene bicyclic ring skeleton, with the S atom positioned adjacent to one of the positions of ring fusion. It has a role as a disinfectant, a platelet aggregation inhibitor, an environmental contaminant, a xenobiotic, a drug allergen and a sensitiser. It is an organonitrogen heterocyclic compound and an organic heterobicyclic compound.
Application	1,2-benzisothiazol-3(2H)-one (BIT) has been widely used in high concentrations for microbial growth control in many domestic and industrial processes, its potential eco-risk should be assessed.
General Description	1,2-Benzisothiazol-3(2H)-one is a commonly used biocide in industrial and consumer products, which possesses antimicrobial activity against gram positive and gram negative bacteria. It is mainly used in packaging, adhesives, detergents, disinfectants, sunscreen lotions, paints and lubricants.
Flammability and Explosibility	Not classified
Contact allergens	1,2-Benzisothiazol-3(2H)-one, both an irritant and a skin sensitizer, is widely used in industry as a preservative in water-based solutions such as pastes, paints, and cutting oils. Occupational dermatitis has been reported mainly due to cutting fluids and greases, in paint manufacturers, pottery moldmakers, acrylic emulsions manufacturers, plumber,printers and lithoprinters, paper makers, analytical laboratory, rubber factory, and employees manufacturing air fresheners. It is also a preservative in vinyl gloves.
