Methyl phenylenediamine

m-Phenylenediamine, also called 1,3-diaminobenzene, is an organic compound with the formula C6H4(NH2)2. It is an isomer of o-phenylenediamine and p-phenylenediamine. This aromatic diamine is a colourless solid that appears as needles, but turns red or purple on exposure to air due to formation of oxidation products. Samples often come as colourless flakes and may darken in storage. WebIn the presence of atmospheric oxygen, a bacterium’s intra-cellular cytochrome oxidase enzymes oxidize the N,N,N,N-tetramethyl- p phenylenediamine dihydrochloride to indophenol, a dark purple-colored end product. This oxidase test is useful in the initial characterization of gram-negative bacteria. Purpose of the test
