5-Sulfosalicylic acid dihydrate Usage And Synthesis
  • Chemical Propertieswhite crystalline powder
  • UsesFor reducing and fixation of proteins in agarose and polyacrylamide gels
  • Purification MethodsCrystallise the acid from H2O. Alternatively, it is converted to the monosodium salt which is crystallised from H2O and washed with a little H2O, EtOH and then Et2O. The acid is recovered by acidifying. The S-4-chlorobenzylisothiuronium salt has m 181o (from dioxane). [Beilstein 11 H 411, 11 II 232, 11 III 704.]
