Web15 sep. 2009 · In the present work, the oxidative coupling reaction of indapamide (an oral antihypertensive diuretic drug) with MBTH in the presence of cerium(IV) was evaluated using distinct reaction approaches and was implemented in an automated multipumping flow system. WebTetramethylbenzidine (TMBZ) is a commonly utilized oxidative chromogenic dye for peroxidase detection on a membrane filter or an EIA plate. Peroxidase catalyses the reduction of hydrogen peroxide to generate two water molecules. TMBZ is the electron source for this reduction.
