Practical aspects in gas chromatography-mass spectrometry for the analysis of pesticide residues in exotic fruits was written by Espana Amortegui, Julio Cesar;Guerrero Dallos, Jairo Arturo. And the article was included in Food Chemistry in 2015.Synthetic Route of C10H12O2 This article mentions the following:
The most relevant parameters of a multimode inlet were optimized to increase the injection volume up to 25 μL using solvent vent mode in order to improve the sensitivity of the gas chromatog.-mass spectrometry system. Consequently, the implementation of a concurrent backflushing was necessary to largely prevent the expected loss of performance derived from such matrix load out of a general-purpose extraction (EN-15622-QuEChERS). Addnl., four mixtures of compounds used as analyte protectants were tested using spiked physalis to enhance the quality of signals. The chosen mixture remarkably improved sensitivity and yield better peak shapes, significantly more than others also tested. The anal. of pesticide residues in exotic fruits using instruments of limited selectivity is challenging since these complex matrixes usually give notably dirty extracts This scheme included an instrumental optimization and the addition of selected compounds that enabled to selectively reach limits of quantitation of 0.01 mg kg-1 for most analytes. In the experiment, the researchers used many compounds, for example, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8Synthetic Route of C10H12O2).
2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Synthetic Route of C10H12O2
