Anwendungen

2-Mercaptobenzothiazole is used for detection of the equivalence point in volumetry (complexometry) and for concentration determinations in colorimetry. It is also used for the photometric determination of gold, cadmium, copper, lead and palladium. Further, it is used as a metalworking fluid, antifreeze, grease, anticorrosive agent, and adhesive. It acts as an antibacterial and antifungal. It is also employed in the rubber industry as a vulcanization accelerator. It inhibits dopamine beta-hydroxylase and biocorrosion in cooling systems, especially in the paper industry. In addition to this, it is used as a wood preservative and rubber additive.

Bemerkungen

Air sensitive. Incompatible with oxidizing agents.
