Piperazines were originally named because of their chemical similarity with piperidine, part of the structure of piperine in the black pepper plant (Piper nigrum). 103-76-4, formula is C6H14N2O, Name is N-(2-Hydroxyethyl)piperazine. The -az- infix added to “piperazine” refers to the extra nitrogen atom, compared to piperidine. It is important to note, however, that piperazines are not derived from plants in the Piper genus. Recommanded Product: N-(2-Hydroxyethyl)piperazine.
Montecinos, Rodrigo;Aliaga, Margarita E.;Pavez, Paulina;Cornejo, Patricio;Santos, Jose G. research published 《 Nucleofugality hierarchy, in the aminolysis reaction of 4-cyanophenyl 4-nitrophenyl carbonate and thionocarbonate. Experimental and theoretical study》, the research content is summarized as follows. Nucleophilic substitution reactions of the title compounds have been investigated with a series of secondary alicyclic amines in several solvents. The solvent, amine, and electrophilic group effects on kinetics, mechanism and nucleofugality hierarchy are discussed from exptl. and theor. studies. These studies show the mechanistic dependence on the solvent polarity; the theor. results indicate that the relative polarization of the reactive centers (C=O and C=S) and the stabilization of the nucleofuges are the main factors in the control of the product distribution.
103-76-4, 1-(2-Hydroxyethyl)piperazine is a useful research compound. Its molecular formula is C6H14N2O and its molecular weight is 130.19 g/mol. The purity is usually 95%.
1-(2-Hydroxyethyl)piperazine is a chemical solvent that is used for the absorption of amines and other compounds. It has been shown to have a high affinity for acidic substances, which may be due to its ability to form hydrogen bonds with them. 1-(2-Hydroxyethyl)piperazine is also used in sample preparation for the analysis of amines and other compounds in fruit extracts. The solubility of 1-(2-Hydroxyethyl)piperazine depends on the experimental conditions, including pH, temperature, and pressure. FT-IR spectroscopy has been used to measure the vibrational modes of 1-(2-Hydroxyethyl)piperazine molecules. The IR spectrum revealed that this compound contains a hydroxyl group and two fatty acid chains with one or more hydroxyl groups at their terminal end. The nmr spectrum showed that 1-(2-Hydroxyethyl)piperazine contains an NH proton as well as, Recommanded Product: N-(2-Hydroxyethyl)piperazine
