| | 5-Sulfosalicylic acid dihydrate Usage And Synthesis |
| Chemical Properties | white crystalline powder | | Uses | 5-Sulfosalicylic Acid Dihydrate is for reducing and fixation of proteins in agarose and polyacrylamide gels. | | Uses | 5-Sulfosalicylic acid dihydrate may be used in the preparation of 1:1 proton-transfer organic adduct, 3-aminopyridin-ium 3-carb-oxy-4-hydroxy-benzene-sulfonate monohydrate and the anhydrous adduct. | | General Description | 5-Sulfosalicylic acid is a strong acid capable of protonating water. It forms a new theophylline complex, which was investigated by X-ray photoelectron spectroscopy (XPS). It forms 1:1 proton-transfer compounds with the ortho-substituted monocyclic heteroaromatic Lewis bases. Their crystal structures have been studied. | | Purification Methods | Crystallise 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.] |
