Application

2-Mercaptobenzothiazole (MBT) has been used in the synthesis of MBT functionalized mesoporous silica which can be used as an adsorbent for the removal of Hg(II) from aqueous solution.

It can also be used as a:
  • Reference compound in photocatalytic activity tests under UV or visible light irradiation.
  • Starting material for the synthesis of conjugates of 2-MBT for antitubercular activity studies.
  • Starting material for the synthesis of 4-thiazolidinones.
