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., Name: 2,2,6,6-Tetramethyl-4-piperidinol

Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist 2403-88-5, formula is C9H19NO, Name is 2,2,6,6-Tetramethyl-4-piperidinol. Auguste Cahours, who named it. Both of them obtained piperidine by reacting piperine with nitric acid. Name: 2,2,6,6-Tetramethyl-4-piperidinol.

Liu, Jiayun;Li, Zhilin;Wang, Min;Jin, Chongyue;Kang, Jin;Tang, Yiwu;Li, Siyan research published 《 Eu2O3/Co3O4 nanosheets for levofloxacin removal via peroxymonosulfate activation: Performance, mechanism and degradation pathway》, the research content is summarized as follows. In this study, Eu2O3/Co3O4 nanosheets (NSs) were successfully synthesized and employed to degrade levofloxacin (LVX) via peroxymonosulfate (PMS) activation. Owing to the enhanced transfer efficiency of Co2+/Co3+ and more adsorbed oxygen, the obtained Eu2O3/Co3O4 NSs displayed better catalytic performance for PMS activation toward LVX degradation than pure Co3O4. The Eu2O3/Co3O4 NSs can remove 97.93% of LVX only in 6 min via activating PMS, with a reaction rate constant (0.2346 min-1) , which was 2.3 folds of single Co3O4 NSs (0.1003 min-1). Besides, Eu2O3/Co3O4 exhibited good catalytic performance in presence of different inorganic anions, satisfactory stability and reusability. Singlet oxygen (1O2), hydroxyl radical (·OH), sulfate radical (SO4·-) and superoxide radical (·O2–) contributed to LVX degradation and 1O2 played the most key role. In addition, based on the ROSs and LVX degradation intermediates, the possible mechanism and degradation pathways of LVX were further cleared in detail. This work can provide a reference for the eco-friendly and facile preparation strategy of efficient and stable catalysts for rapid and efficient removal of recalcitrant pollutants.
