Chondroitin disaccharide di-diSB trisodium saltChondroitin disaccharide di-diSB trisodium salt is a chondroitin sulfate binding agent that can be used in the diagnosis of subcutaneous tumors. It binds to the chondroitin sulfate component of proteoglycans and stains these proteins under light microscopy. This agent can also be used to detect monoclonal antibodies that bind to the chondroitin sulfate component of proteoglycans. The detection of this agent may be done by enzyme-linked immunosorbent assay or fluorescence microscopy.CAS Number136132-71-3Product NameChondroitin disaccharide di-diSB trisodium saltIUPAC Nametrisodium;(3R,4S)-2-[(3R,4R,5R,6R)-3-acetamido-2-hydroxy-6-(hydroxymethyl)-5-sulfonatooxyoxan-4-yl]oxy-4-hydroxy-3-sulfonatooxy-3,4-dihydro-2H-pyran-6-carboxylateMolecular FormulaC14H18NNa3O17S2Molecular Weight605.377InChIInChI=1S/C14H21NO17S2.3Na/c1-4(17)15-8-11(10(32-34(25,26)27)7(3-16)28-13(8)21)30-14-9(31-33(22,23)24)5(18)2-6(29-14)12(19)20;;;/h2,5,7-11,13-14,16,18,21H,3H2,1H3,(H,15,17)(H,19,20)(H,22,23,24)(H,25,26,27);;;/q;3*+1/p-3/t5-,7+,8+,9+,10-,11+,13?,14?;;;/m0…/s1InChI KeyQTXFYAVTBRRGLE-QYAHXJAGSA-KSMILESCC(=O)NC1C(C(C(OC1O)CO)OS(=O)(=O)[O-])OC2C(C(C=C(O2)C(=O)[O-])O)OS(=O)(=O)[O-].[Na+].[Na+].[Na+]
