CAS:<p>4-Aminobenzenesulfonic acid is a sulfonic acid that is used in wastewater treatment. It has been shown to be an excellent water permeability agent and can be used as an additive to the process of making sulfonated polymers for use in water filtration. 4-Aminobenzenesulfonic acid has been shown to have enzyme inhibitory effects on metal hydroxide-dependent enzymes, such as sulphanilic and sulfanilic acid. This compound also has been investigated as a potential therapeutic agent for the treatment of cancer, with some success. It has been shown to stimulate the production of picolinic acid, which is an intermediate in the kynurenine pathway leading to production of nicotinamide adenine dinucleotide (NAD+). In humans, 4-aminobenzenesulfonic acid can bind toll-like receptors (TLRs) and activate TLR4 signaling pathways.</p>Formula:C6H7NO3SPurity:Min. 95%Molecular weight:173.19 g/molSulfanilic acid, ACS, 98.0-102.0%
