4,4',4''-Nitrilotribenzoic acid is a low molecular weight activated compound with a hexane molecule and luminescence properties. This compound has been used in the detection of human pathogens, for example, Salmonella enterica serovar Typhimurium. The uptake of 4,4',4''-nitrilotribenzoic acid by these bacteria has been shown to be due to its peroxidase-like activity. 4,4',4''-Nitrilotribenzoic acid has also been used for the activation of polybenzimidazole and for polymerization reactions in polybenzimidazole films. The time required for polymerization depends on the concentration of 4,4',4''-nitrilotribenzoic acid used.
