N,N,N',N'-Tetramethyl-1,4-Phenylenediamine Dihydrochloride (TMPD) (CAS: 637-01-4) is an oxidizable compound that serves as a reducing co-substrate for heme peroxidases. TMPD is also used as a test reagent in microbiology for the classification of cytochrome oxidase positive aerobic microorganisms. It finds application as a detection of peroxidases on polyacrylamide gels. TMPD has been used to determine the oxidase activity displayed by various microorganisms. TMPD is commonly used to perform the oxidase test for the colorimetric identification of pathogenic and non-pathogenic bacteria. For oxidase reagent, use a 1% aqueous solution of TMPD.
