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. Electric Literature of 103-76-4.
Yan, Longjia;Li, Yongliang;Deng, Minggao;Chen, Anchao;Du, Zhiyun;Dong, Changzhi;Chen, Huixiong research published 《 Design, synthesis and biological activities of compounds containing 1,3,4-oxadiazole or 1,3,4-thiadiazole》, the research content is summarized as follows. In order to find new anti-tumor drugs, a series of novel 1,3,4-oxadiazole and 1,3,4-thiadiazole derivatives were designed and synthesized. The target compounds were evaluated for antitumor activity in vitro on four human cancer cell lines including B-16 (skin melanoma cells), PC-3 (human prostate cancer cells), U87 (human primary glioblastoma cells) and A549 (human non-small cell lung cancer cells). The results displayed that some of the compounds had good activities, especially, 5-((6-(4-(2-hydroxyethyl) piperazin-1-yl)-2-methylpyrimidin-4-yl) amino)-N-(2-methoxyphenyl)-1,3,4-thiadiazole-2-carboxamide (8b) and 5-((6-(4-(2-hydroxyethyl) piperazin-1-yl)-2-methylpyrimidin-4-yl) amino)-N-(4-methoxyphenyl)-1,3,4-thiadiazole-2-carboxamide (8c) showed high antitumor activities against four cancer cell lines, which was better than dasatinib. These compounds were further studied for their possible target of tumor suppression.
Electric Literature 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.
