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. Formula: C9H19NO.
Barrios, Benjamin;Mohrhardt, Benjamin;Doskey, Paul V.;Minakata, Daisuke research published 《 Mechanistic Insight into the Reactivities of Aqueous-Phase Singlet Oxygen with Organic Compounds》, the research content is summarized as follows. Singlet oxygen (1O2) is a selective reactive oxygen species that plays a key role for the fate of various organic compounds in the aquatic environment under sunlight irradiation, engineered water oxidation systems, atm. water droplets, and biomedical systems. While the initial rate-determining charge-transfer reaction mechanisms and kinetics of 1O2 have been studied extensively, no comprehensive studies have been performed to elucidate the reaction mechanisms with organic compounds that have various functional groups. In this study, we use d. functional theory calculations to determine elementary reaction mechanisms with a wide variety of organic compounds The theor. calculated aqueous-phase free energies of activation of single electron transfer and 1O2 addition reactions are compared to the exptl. determined rate constants in the literature to determine linear free-energy relationships. The theor. calculated free energies of activation for the groups of phenolates and phenols show excellent correlations with the Hammett constants that accept electron densities by through-resonance. The dominant elementary reaction mechanism is discussed for each group of compounds As a practical implication, we demonstrate the fate of environmentally relevant organic compounds induced by photochem. produced intermediate species at different pH and evaluate the impact of predicting rate constants to the half-life.
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., Formula: C9H19NO
