2,5-Dioxopyrrolidin-1-yl 3′,6′-dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-5-carboxylate (cas: 92557-80-7) belongs to benzofurans derivatives.Benzofuran is one of the most significant oxygen-containing heterocycles consisting of fused benzene and furan ring, which are widely presented in various naturally occurring and synthetically active compounds. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antiviral, antimicrobial, antitumor, anti-inflammatory.Application of 92557-80-7

Development of a temperature gradient focusing method for in situ extraterrestrial biomarker analysis was written by Danger, Gregoire;Ross, David. And the article was included in Electrophoresis in 2008.Application of 92557-80-7 This article mentions the following:

Scanning temperature gradient focusing (TGF) is a recently described technique for the simultaneous concentration and separation of charged analytes. It allows for high analyte peak capacities and low LODs in microcolumn electrophoretic separations In this paper, the authors present the application of scanning TGF for chiral separations of amino acids. Using a mixture of seven carboxyfluorescein succinimidyl ester-labeled amino acids (including five chiral amino acids) which constitute the Mars7 standard, the authors show that scanning TGF is a very simple and efficient method for chiral separations The modulation of TGF separation parameters (temperature window, pressure scan rate, temperature range, and chiral selector concentration) allows optimization of peak efficiencies and analyte resolutions The use of hydroxypropyl-β-cyclodextrin at low concentration (1-5 mmol/L) as a chiral selector, with an appropriate pressure scan rate (-0.25 Pa/s) and with a low temperature range (3-25° over 1 cm) provided high resolution between enantiomers (Rs >1.5 for each pair of enantiomers) using a short, 4 cm long capillary. With these new results, the scanning TGF method appears to be a viable method for in situ trace biomarker anal. for future missions to Mars or other solar system bodies. In the experiment, the researchers used many compounds, for example, 2,5-Dioxopyrrolidin-1-yl 3′,6′-dihydroxy-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-5-carboxylate (cas: 92557-80-7Application of 92557-80-7).
