应用

3,3′,5,5′-四甲基联苯胺（TMB）是一种二氨基联苯胺的非致癌性取代物（Ames测试阴性）适合在ELISA实验中作为过氧化物酶底物。底物产生可溶性终产物，淡蓝色，分光光度检测在370或620-650nm可以读峰值。TMB反应能被2M H₂SO₄终止（产生黄色），在450nm处可读。一种高敏感，特异性试剂用于检测血液，血红蛋白实验，过氧化物酶实验。

3,3′,5,5′-Tetramethylbenzidine may be used as a substrate for the analysis of diclofenac in water samples and dextromethorphan and its major metabolite dextrorphan in urine samples using enzyme-linked immunosorbent assay (ELISA) and gas chromatography coupled to mass spectrometry (GC-MS).
