Application of 33100-27-5. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane. In a document type is Article, introducing its new discovery.
Selective Reagents in Chemical Ionization Mass Spectrometry: Diisopropyl Ether
Dilute mixtures of diisopropyl ether in nitrogen, methane, or helium can serve as useful reagent gases for analytical problems where relatively gentle ionization like that of NH3 is desired but for which NH3 does not give satisfactory results.Diisopropyl ether acts as a proton transfer chemical ionization reagent gas, gives minimal solvation with most species, and gives higher relative sensitivity than ammonia for compounds which undergo the base-switching reaction.Some indications of the steric environments of the site of protonation are noted.The abundant reagent ions of diisopropyl ether at m/z 103, 87, and 61 may interfere with the analysis of samples which give ions at those masses.
