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. Name: 2,2,6,6-Tetramethyl-4-piperidinol.
Rayaroth, Manoj P.;Oh, Dasom;Lee, Chung-Seop;Kumari, Nitee;Lee, In Su;Chang, Yoon-Seok research published 《 Carbon-nitride-based micromotor driven by chromate-hydrogen peroxide redox system: Application for removal of sulfamethaxazole》, the research content is summarized as follows. In this study, a Janus Fe/C3N4 micromotor driven by a chromate-hydrogen peroxide (Cr(VI)/H2O2) redox system was developed and its movement was analyzed. The motion of the micromotor was tracked via nanoparticle tracking anal. (NTA) and the corresponding diffusion coefficients (D) were determined The NTA results revealed that D = 0 in water in the absence of additives (Cr(VI) or H2O2). The addition of H2O2 resulted in an increase in D from 0 to 12 x 106 nm2 s-1, which further increased to 20 x 106, 26.5 x 106, 29 x 106, and 44 x 106 nm2 s-1 with the addition of 0.5, 1, 2, and 5 ppm of Cr(VI), resp. Cr(VI) alone did not efficiently propel the Fe/C3N4-based micromotor. Therefore, it was proposed that the Cr(VI)/H2O2 redox system generates O2, which plays a major role in the movement of the C3N4-based micromotor. In addition, the formation of reactive species, such as ·OH and 1O2, was confirmed through ESR experiments The reactive species efficiently degraded sulfamethaxazole (SMX), an organic pollutant, as demonstrated through degradation studies and product analyses. The effects of various parameters, such as H2O2 concentration, Cr(VI) concentration, and initial pH on the movement of micromotor and degradation of SMX were also documented.
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
