N,N,N',N'-四甲基对苯二胺二盐酸盐 用途与合成方法
N,N,N',N'-四甲基对苯二胺二盐酸盐又叫盐酸四甲基对苯二胺，简称TMPD，是一种氧化酶试剂，可用于鉴别淋球菌。
N,N,N',N'-四甲基对苯二胺二盐酸盐又叫盐酸四甲基对苯二胺，可用于鉴别淋球菌。其原理是淋球菌具有氧化酶，它产生的氧离子能将氧化酶试剂（N,N,N',N'-四甲基对苯二胺二盐酸盐）氧化成醌类化合物，出现颜色反应。
TMPD dihydrochloride，一种易于氧化的化合物，是一种酶促转化的氧化还原活性底物分子。TMPD dihydrochloride 也是一种电子供体，并作为血红素过氧化物酶的还原共底物。TMPD dihydrochloride 也是一种 complex IV 的底物。TMPD (N,N,N′,N′-tetramethyl-para-phenylene-diamine) is used in cell culture and microbiology to differentiate organisms that exhibit cytochrome c oxidase activity and to distinguish between Gram-negative and Gram-positive pathogenic and non-pathogenic bacteria. The concept of TMPD oxidation by microorganisms is widely used and is known as a successful colorimetric indicator for bacterial oxidases, as the radical cation TMPD+˙, formed by oxidation, shows a characteristic deep blue colour. The electrochemical recognition of the TMPD oxidation by bacterial oxidases can be applied to a variety of pathogens.
