2-Mercaptobenzothiazole (2-MBT) is widely used as a vulcanisation accelerator and is contained in many products made from natural rubber, e.g. car tires. Additionally, it is used as a fungicide in paint or fibre. Systemically human exposure to 2-MBT can occur via dermal and oral uptake or inhalation. Locally, 2-MBT can cause skin sensitisation.

2-MERCAPTOBENZOTHIAZOLE
Three metabolites, among four detected, were identified. 2-Mercaptobenzothiazole (MBT) is the most important and most widely used member of the benzothiazole (BT) family. MBT is typically a rubber additive, but it has also other applications, such as inhibiting biocorrosion in
Abstract: 2-mercaptobenzothiazole (MBT) is a chemical compound which is widely used in various processes in chemical industry, and it was also detected in environmental samples. Most of the researchers employed liquid chromato-graphy (LC) or gas chromatography (GC) for determination of MBT. When GC was used, derivatization was necessary in

Mercaptobenzothiazole Wikipedia
Mercaptobenzothiazole. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 2-Mercaptobenzothiazole is an organosulfur compound with the formula C6H4(NH)SC=S. It is used in the sulfur vulcanization of rubber.
2-Mercaptobenzothiazole (MBT) is used as a vulcanization accelerator in rubber products that come into contact with potable drinking water. When such products are evaluated for contact with potable water and submitted for ANSI/NSF Standard 61 certification, any chemical extracting from these products must be below an appropriate action level of exposure.
- Where is 2-mercaptobenzothiazole commonly found?
- You are most likely to contact 2-mercaptobenzothiazole when using, wearing, or handling natural or synthetic rubber products at work or at home. Work shoes and athletic shoes are often made with rubber components that contain mercaptobenzothiazole or related substances.
- What is 2 mercaptobenzothiazole used for?
- 2 mercaptobenzothiazole (MBT) is used as an electroplating additive, also known as an acid copper plating brightener. It is mainly used as a brightener for bright copper sulfate in paving. It has a good leveling effect. The general dosage is 0.05-0.10 g/L.
- What is the relative density of 2-mercaptobenzothiazole?
- The relative density of 2-mercaptobenzothiazole (MBT) is between 1.41 and 1.48. 2-mercaptobenzothiazole is poorly soluble in water and n-hexane, but is easily soluble in acetone and slightly soluble in benzene. It is an acidic compound. Vulcanization promotes strong bonds and the vulcanization curve is relatively flat. 2-mercaptobenzothiazole is also less polluting.
- What happens if 2 mercaptobenzothiazole is substituted into C6?
- The substitution of the same substituent into the C6 (R 2 in Scheme 1) position of the phenyl ring of the 2-mercaptobenzothiazole resulted in a slight shift toward a higher wavelength (bathochromic shift) when compared to the compound with substitution into the C5 (R 1 in Scheme 1) position.
- What happens if 2 mercaptobenzothiazole reacts with Z and E sulfoxides?
- Reaction of Z and E isomeric sulfoxides with 2-mercaptobenzothiazole led to the splitting of thiazolidine ring in penicillin nucleus and to the formation of (E) and (Z)-alkylidene-4-heteroaryldithioazetidin-2-ones 5–6 and 7–11 (Fig. 4).
- Are 2-mercaptobenzothiazole derivatives good antiproliferative in gastric cancer?
- A very recent work by Song and coworkers identified novel 2-mercaptobenzothiazole derivatives displaying good antiproliferative activity in gastric cancer . The authors designed compounds as potential colchicine binding site tubulin inhibitors and as activators of Hippo pathway.
