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. Application In Synthesis of 103-76-4.
Khan, Azam;Hayat, Faisal;Butler, Ian S.;Nawaz Tahir, Muhammad;ur Rehman, Zia research published 《 Mercury(II) dithiocarbamates: Structural aspects and their use as single-source precursors for shape-controlled facile synthesis of HgS nanoparticles》, the research content is summarized as follows. A single-source, precursor strategy has been adopted for the shape-controlled synthesis of HgS nanoparticles (NPs) in which Hg(II) dithiocarbamate complexes are used as the starting materials. The precursor complexes bis(4-benzhydrylpiperazine-1-carbodithioate-κ2 S,S’)mercury(II), bis(4-benzylpiperazine-1-carbodithioate-κ2 S,S’)mercury(II), bis(4-hydroyethylpiperazine-1-carbodithioate-κ2 S,S’)mercury(II), bis(4-benzylpiperidine-1-carbodithioate-κ2 S,S’)mercury(II) and propane-1,3-diyl-bis(piperidincarbamodithioate)mercury(II), termed as [Hg(L1)2] to [Hg(L5)2] resp., were characterized by chem. anal. (CHNS), FT-IR, 1H and 13C NMR spectroscopy. Two of the complexes, [Hg(L1)2] and [Hg(L2)2], were also subjected to single-crystal XRD anal. to recognize their mol. and supramol. features. The conversion of the precursor complexes to HgS NPs was achieved by their thermolysis in ethylenediamine (en) at ambient pressure and low temperature in the absence of any externally added toxic surfactant. The morphol., structure, phase and elemental composition of the resulting HgS NPs were analyzed by SEM, PXRD and EDS techniques. The SEM results revealed a significant precursor-based morphol. variation in the HgS NPs, which could be attributed to the stability/solubility of the initial precursor complex in ethylenediamine and to the presence of a capping agent on the particle surfaces (as revealed by DFT studies and FT-IR anal.). The PXRD patterns showed that the HgS NPs grow in two typical cystalline forms – cubic (black) and hexagonal (red). The optical properties of the NPs were assessed by UV-Visible spectroscopy, which confirmed that they have a good absorption ability in the visible region.
Application In Synthesis of 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, 103-76-4.
