102062-36-2 - Reference Information
| Uses | N-(3-sulfopropyl)-3,3 ',5,5'-tetramethylbenzidine sodium salt can be used to prepare free chlorine sensitive dyes, ideal free chlorine sensitive dyes include one or more colorants selected from tetraalkylbenzidine compounds. |
| Biological properties | Tetraalkylbenzidine compound is an oxidative chromophoric colorant that has an absorption peak at a wavelength of about 450 to 470nm when reacting with free chlorine in an acidic sample, and its coloring is yellow to blue-green. Commonly used tetraalkyl benzidine compounds include N-(2-sulfoethyl)-3,3 ',5,5'-tetramethylbenzidine; N-(3-sulfopropyl)-3,3 ',5,5'-tetramethylbenzidine sodium salt; N-(4-sulfobutyl)-3,3 ',5,5'-tetramethylbenzidine; N-(2-hydroxy-2-sulfoethyl)-3,3 ',5,5'-tetramethylbenzidine; N-(2-hydroxy-3-sulfopropyl)-3,3 ',5,5'-tetramethylbenzidine; N-(2, 4-disulfobenzyl)-3,3 ',5,5'-tetramethylbenzidine and its alkali metal salts, among these compounds, it is particularly preferred to use compounds in the form of sodium salts, which have high water solubility and are hardly crystallized at room temperature. N-(3-sulfopropyl)-3,3 ',5,5'-tetramethylbenzidine sodium salt (TMB-PS) selectively reacts with free chlorine in the presence of chloramine to give a yellow species, λmax = 467nm. |
| biological activity | TMB-PS(102062-36-2) is N-(3-sulfoppyl)-3,3 ',5,5'-tetramenthylbenzidine sodium salt, soluble in water, Can be used in various ph environments. |
