Collection of ion-trap mass spectra of sulfonylurea pyrolysis products was written by Galletti, Guido C.;Dinelli, Giovanni;Chiavari, Giuseppe. And the article was included in Journal of Mass Spectrometry in 1995.Synthetic Route of C8H10ClNO3S This article mentions the following:
The pyrograms of 14 sulfonylureas, i.e. herbicides characterized by high biol. activity and low application dose are discussed and the mass spectra of over 30 relevant pyrolysis products as obtained with a heated filament pyrolyzer interfaces to a capillary gas chromatograph/ion-trap detector mass spectrometer are presented. Such a data compilation is useful for diagnostic purposes for both intact sulfonylureas and their metabolites after determination in soil, because metabolites and pyrolysis products are often identical and most of their mass spectra are lacking in com. available mass spectral libraries. The performance of the ion-trap detector based on the quality of the mass spectra is briefly discussed. In the experiment, the researchers used many compounds, for example, 2-(2-Chloroethoxy)benzenesulfonamide (cas: 82097-01-6Synthetic Route of C8H10ClNO3S).
2-(2-Chloroethoxy)benzenesulfonamide (cas: 82097-01-6) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Synthetic Route of C8H10ClNO3S
