N’-Tetramethyl-p-phenylenediamine dihydrochloride_Kain Industrial Additive

Background and overview[1][2] N,N,N’,N’-tetramethyl-p-phenylenediamine dihydrochloride, also called tetramethyl-p-phenylenediamine hydrochloride, or TMPD for short, is an oxidase reagent that can be used to identify gonococci. . The principle is that Neisseria gonorrhoeae has an oxidase, and the oxygen ions it produces can oxidize the oxidase reagent (N,N,N’,N’-tetramethyl-p-phenylenediamine dihydrochloride) into quinone compounds, and the color appears. reaction.…
