2403-88-5, 2,2,6,6-Tetramethyl-4-piperidinol(TEMPO) is a useful research compound. Its molecular formula is C9H19NO and its molecular weight is 157.25 g/mol. The purity is usually 95%.
TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., Quality Control of 2403-88-5

Zhang, Yunfei;Niu, Junfeng;Xu, Jianhui research published 《 Fe(II)-promoted activation of peroxymonosulfate by molybdenum disulfide for effective degradation of acetaminophen》, the research content is summarized as follows. This work demonstrated that Fe ion was an effective promoter of bulk MoS2 to activate peroxymonosulfate (PMS) to degrade acetaminophen (ACT). The ACT removal rate constant in the presence of 5 mg/L FeSO4·7H2O (0.1099/min) was ∼20 times that in the absence of FeSO4•7H2O (0.0045/min) with 0.1 g/L MoS2/FeSO4·7H2O at pH0 3. ESR characterization and quenching experiments suggested the key role of singlet oxygen (1O2), acting as dominant reactive species responsible for ACT degradation in the Fe2+/MoS2/PMS system. The MoS2 chem. state and composition, ion concentrations (Fe, Mo) concentrations, and Mo6+ speciation were examined Results suggested the Fe2+ promoting effect originated from Fe2+ regeneration mediated by MoS2, and formation of the molybdenum(VI) peroxo complex species in the Fe2+/MoS2/PMS system. This work provided insight into PMS activation by MoS2 accelerated by Fe2+ and suggested a highly efficient, easy-to-handle, environment-friendly method to treat refractory wastewater.
