What is 5-Chloro-2-mercaptobenzothiazole ?
Chemical properties
LIGHT YELLOW TO YELLOW-GREEN GRANULAR POWDER
The Uses of 5-Chloro-2-mercaptobenzothiazole
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.
What are the applications of Application
5-Chloro-2-mercaptobenzothiazole is employed in the analysis of peptidoglycan muropeptides
General Description
