Formula: C9H19NO, 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 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. Formula: C9H19NO.

Khan, Ajmir;Rabnawaz, Muhammad research published 《 Base-Layer-Driven Self-Healing Materials》, the research content is summarized as follows. Despite the enormous potential applications for intrinsic self-healing materials, these materials have reached a road-block where concurrent excellent mech. properties and autonomous self-healing behavior are impossible. Herein reported is a base-layer-driven self-healing (BLDS) approach that facilitates self-healing irresp. of the glass transition (Tg) or melting temperature (Tm) of the top layer. The BLDS approach enables autonomous self-healing materials that concurrently offer ultramech. durability and ambient healing. The BLDS relies on an ambient healable base layer and a structural/functional top layer. In this study, the bottom layer is prepared using reversible-dynamic covalent linkages in polyurethane/urea. Meanwhile, the top layer is selected from a thermoplastic (e.g., polylactic acid), thermoset (e.g., polyurethane), and functional thermosets (e.g., omniphobic urethane). The resultant dual-layer coatings/films offer a modulus of >800 MPa and still maintained excellent ambient self-healing. The antirust efficacy of the BLDS coating is also demonstrated. As the top layer can be selected from any com. structural and functional materials, this work opens a whole different direction for autonomous healable materials, which will open addnl. avenues of real-world applications.
