analysis of mercaptobenzothiazole (mbt) compounds from sulfur
a lc-ms-ms method was developed analyze mbt in the mtbe extracts of sulfur cured rubber. the method is specific for mbt and it linear over 50 1000 ng/ml. the method is reproducible for extractable mbt determination. the percent recovery of mbt is 87.7% at 400 ng/ml level. the dl of mbt is 6 ng/ml or 12 pg on column.

2 mercaptobenzothiazole an overview sciencedirect topics
2-mbt is used as a vulcanization accelerator especially in rubber products like car tires, cables, seals, shoes, rubber gloves and toys (baua, 2001; bfr, 2008). therefore, a general possible exposure of the population to 2-mbt can be supposed. fukuoka and tanaka suggested the metabolism pattern in rats (fukuoka et al., 1995).
substance evaluation report echa,articles, it needs to be noted that use of other vulcanisation agents than 2-mbt (e.g. n-cyclohexyl-2-benzothiazole sulphonamide and 2-mercaptobenzothiazyl disulfide) may also release 2-mbt during their intended use. the exposure assessment performed by the registrants indicates the level of dermal consumer
recent developments in conducting polymers: applications for,cps have advantages such as controllable chemical/electrochemical properties and adjustable electrical conductivities from 10 −11 to 10 5 s cm −1 upon doping . they are soft and extendable, similar to conventional polymers. 41,42. fig. 2. (a) chemical structures of several cps. (b) electrical conductivity range of cps.
- Who is exposed to MBT?
- In the studies evaluated by the IARC Monographs Working Group, exposure to high amounts of MBT in humans occurred in workers in the chemical industry, but workers in the rubber or tyre-manufacturing industries may also be exposed to MBT.
- Why is MBT represented by two different structures?
- The molecular structures of the analyzed compounds prior to degradation are shown in Figure 1. MBT is represented by two different structures because this additive can be present in two tautomeric forms (Figures 1v and 1vi) .
- How effective is a benzothiazole derivative against MDA-MB-231 cells?
- A novel benzothiazole derivative bearing indole-based moiety 4 exhibited an excellent anti-tumor activity with IC 50 values of 0.84 and 0.88 μM against A549 cells and MDA-MB-231 cells, respectively.
