2,3,5-Triphenyltetrazolium chloride (≥98 %) : 50 grams

2,3,5-Triphenyltetrazolium chloride (TTC) is a high-purity redox indicator commonly used in cell viability assays, microbial respiration studies, and plant tissue testing. At ≥98% purity, TTC serves as an efficient electron acceptor, forming red formazan upon reduction in living cells — a key indicator of metabolic activity.
