Analysis of extractable organic compounds in water by gas chromatography mass spectrometry: applications to surface water was written by Deroux, J. M.;Gonzalez, C.;Le Cloirec, P.;Kovacsik, G.. And the article was included in Talanta in 1996.Application In Synthesis of 5-Methylisobenzofuran-1(3H)-one This article mentions the following:
Over a period of 1 yr, the surface water of a canal network (Languedoc-Roussillon area, France) was analyzed in order to identify organic compounds and to monitor its quality. Pollutants were extracted from 19 L of raw water using methylene chloride in a continuous countercurrent liquid-liquid extractor with a pulsed column. The extraction was performed at a pH above 11 and again at a pH below 2 according to U.S. Environmental Protection Agency method 625. The extract was analyzed by gas chromatog./mass spectrometry, using two ionization techniques, namely electron ionization and chem. ionization. Mass spectra obtained by electron ionization were compared with those in a database (NIST). Some natural compounds and micropollutants were identified. Their structures were confirmed by chem. ionization (methane). One hundred and ten substances, making up the broad spectrum of extractable compounds in the surface water studied, were found by this method at a nanogram per L concentration level. Among them, 13 are priority pollutants. These specific pollutants were qualified. In the experiment, the researchers used many compounds, for example, 5-Methylisobenzofuran-1(3H)-one (cas: 54120-64-8Application In Synthesis of 5-Methylisobenzofuran-1(3H)-one).
5-Methylisobenzofuran-1(3H)-one (cas: 54120-64-8) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.Application In Synthesis of 5-Methylisobenzofuran-1(3H)-one
