Recommanded Product: 2,2,6,6-Tetramethyl-4-piperidinol, 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., 2403-88-5.

Piperidine the name comes from the genus name Piper, which is the Latin word for pepper. 2403-88-5, formula is C9H19NO, Name is 2,2,6,6-Tetramethyl-4-piperidinol. Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids, such as natural-occurring solenopsins. Recommanded Product: 2,2,6,6-Tetramethyl-4-piperidinol.

Sun, Hongwei;He, Fei;Choi, Wonyong research published 《 Production of Reactive Oxygen Species by the Reaction of Periodate and Hydroxylamine for Rapid Removal of Organic Pollutants and Waterborne Bacteria》, the research content is summarized as follows. Periodate (PI, IO4–) can be activated by hydroxylamine (HA), resulting in rapid removal of organic pollutants (within seconds). While previous studies on PI-based advanced oxidation processes proposed iodate radical (•IO3) as the major reactive species, no evidence of •IO3 production was observed in the present PI/HA system. Reactive oxygen species (ROS) including •OH, HO2•, and 1O2, are proposed to be the main oxidants of the PI/HA system, as supported by tests using scavengers, chem. probes, and spin-trapping ESR. To minimize the risk of toxic iodinated byproduct formation caused by reactive iodine species, e.g., HOI and I2, the HA:PI molar ratio was optimized at 0.6 to achieve a stoichiometric conversion of IO4– to iodate (IO3–), a preferred non-toxic I species sink. The PI/HA system also efficiently inactivated Gram-pos. and Gram-neg. bacteria, producing 1O2 as the dominant disinfectant. The ROS production mechanism was also assessed and is discussed in detail. This work offers a simple, highly efficient option for PI activation and ROS production which may find useful applications where urgent, rapid toxic pollutant removal is needed.
