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., Reference of 2403-88-5

Tan, Chaoqun;Li, Peng;Xu, Tianhui;Yu, Hui;Chen, Kaiyang;Xiang, Huiming;Su, Lianghu research published 《 Crystal boron significantly enhances pollutants removal kinetics by Fe0/PMS system》, the research content is summarized as follows. Numerous challenges arise during zero-valent iron (Fe0) utilization in environmental catalysis, including low reactivity and reactivity reduction with time. In this study, crystal boron (C-boron) was used as a metal-free cocatalyst to enhance the efficiency of Fe0/peroxymonosulfate (PMS) activation. Flunixin meglumine (FMME), aspirin (ASA), nitrobenzene (NB), and benzoic acid (BA) were examined as target contaminants. Exptl. results showed that their resp. removal efficiency reached 98.1, 68.8, 17.5, and 83.3% within 20 min at initial pH 4.0 and a C-boron dosage of 150 mg/L in C-boron/Fe0/PMS system, with a huge fold increase of the apparent rate constants (3-135 times for the four pollutants) than that in Fe0/PMS system. Furthermore, reactive species of ·OH, SO-·4, and 1O2 were confirmed in C-boron/Fe0/PMS system by quenching and in-situ ESR (EPR) tests, and the contribution ratios of ·OH and SO-·4 were turned out to be 3.6% and 75.3%. This study revealed dual-cycle systems (boron/boron oxide, Fe2+/Fe3+) cooperate to improve the catalytic effect significantly. The results in the growth of algal cells showed that C-boron addition in Fe0/PMS system could lead to the decrease of biol. toxicity.
