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

DescriptionBIT 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 PropertiesYellow Powder

UsesAntimicrobial agent.

UsesIsothiazolinone 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.

Usespreservative in cooling fluids, paints, adhesives paper and in the textile industry

DefinitionChEBI: 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.

Contact allergensBIT, 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.

Safety ProfileModerately toxic by ingestion.When heated to decomposition it emits toxic vapors ofNOx and SOx.
