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.

Application

5-Sulfosalicylic acid dihydrate may be employed for the quantification of doxorubicin derived from PEGylated liposomal doxorubicin (Doxil) and its major metabolite in human plasma by HPLC. It may be used in the preparation of poly[[tris(di-2-pyridylamine)tris([μ]-5-sulfonatosalicylato)tricopper(II)] trihydrate].
5-Sulfosalicylic acid (3.5%) in 12% trichloroacetic acid is commonly used as a fixing solution for proteins in agarose and polyacrylamide gels.

Analysis Note

Tested for use in fixing solutions for PAGE, SDS-PAGE and IEF.
