In situ organic compound analysis on a meteorite surface by desorption electrospray ionization coupled with an Orbitrap mass spectrometer was written by Naraoka, Hiroshi;Hashiguchi, Minako. And the article was included in Rapid Communications in Mass Spectrometry in 2018.Recommanded Product: 1-Octyl-1H-imidazole This article mentions the following:
Rationale : Since extraterrestrial organic matter in meteorites is a very complex mixture that is hard to ionize due to its association with minerals, in situ anal. of polar organic compounds has never been performed. When studying powd. samples, spatial information of organic compounds is lost. Methods : In situ mol. anal. and chem. imaging of polar organic compounds were performed on a meteorite surface by desorption electrospray ionization coupled with high-resolution mass spectrometry (DESI-HRMS) using an Orbitrap mass spectrometer. Results : Many CHN compounds, including alkylated pyridine and imidazole homologs, were identified from the complex peaks by HRMS using a spray of elec. charged methanol with a spatial resolution of ∼50 μm. The same alkylated homologs have the same spatial distribution in the meteorite matrix, while alkylpyridines occur in a different location from alkylimidazoles. Conclusions : The compound distribution suggests a different source for each compound series or a chromatog. separation effect associated with fluid movement in the meteorite parent body. The DESI-HRMS imaging will further the authors’ understanding of organic compound distribution with respect to mineral and water interactions in meteorites. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Recommanded Product: 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Recommanded Product: 1-Octyl-1H-imidazole
