Description
4-Chlorobenzenesulfonic acid is soluble in water and ethanol. Prepared by sulfonation of chlorobenzene with sulfuric acid; the water formed in the reaction is removed continuously. It can be hydrolyzed to chlorobenzene with steam at 190℃ and is used in the manufacture of 4-chloro-3-nitroben- zenesulfonic acid.
Chemical Properties
greyish-beige flaked solid
Uses
4-Chlorobenzenesulfonic acid was employed as anion dopants for the matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS) of neutral oligosaccharides.
General Description
4-Chlorobenzenesulfonic acid is the major polar by-product formed during the chemical synthesis of 1,1,1-trichloro-2,2-
bis-(4-chlorophenyl)ethane (DDT).
