General description

5-Chloro-2-mercaptobenzothiazole(CMBZT) reacts with iodine in a molar ratio of 1:1 to form charge-transfer complex (CMBZT)I2.

Application

5-Chloro-2-mercaptobenzothiazole (CMBZT) has been used in the analysis of lipopolysaccharide by negative-ion matrix-assisted laser desorption ionization-time of flight mass spectrometry. It has been used in the synthesis of the new mixed ligand silver(I) chloride complex with the heterocyclic thioamide CMBZT and tri(p-tolyl)phosphine. Found to be more sensitive than DHB for analysis of high mannose N-linked glycans. Used in analysis of peptidoglycan muropeptides.
