Carboxymethyl-b-cyclodextrinCarboxymethyl-?-cyclodextrin is a cationic cyclodextrin that is used as a carrier for drugs. It has been shown to be able to bind nonsteroidal anti-inflammatory drugs (NSAIDs) with high affinity and selectivity. Carboxymethyl-?-cyclodextrin has also been shown to have a high stability in human serum and urine, as well as redox potentials that are close to physiological conditions. In addition, it can be easily detected by titration calorimetry and antibody binding assays. Carboxymethyl-?-cyclodextrin has been used in pharmaceutical preparations, including monoclonal antibody production and wastewater treatment.CAS Number218269-34-2Product NameCarboxymethyl-beta-cyclodextrinIUPAC Name2-[[(1R,3R,5R,6S,8R,10R,11S,13R,15R,16S,18R,20R,21R,23R,25R,26R,28R,30R,31R,33R,35R,36R,37R,38R,39R,40R,41R,42R,43R,44R,45R,46R,47R,48R,49R)-36,38,40,42-tetrakis(carboxymethoxy)-10,15-bis(carboxymethoxymethyl)-37,39,41,43,44,45,46,47,48,49-decahydroxy-20,25,30,35-tetrakis(hydroxymethyl)-2,4,7,9,12,14,17,19,22,24,27,29,32,34-tetradecaoxaoctacyclo[31.2.2.23,6.28,11.213,16.218,21.223,26.228,31]nonatetracontan-5-yl]methoxy]acetic acidMolecular FormulaC56H84O49Molecular Weight1541.239InChIInChI=1S/C56H84O49/c57-1-15-42-47(89-12-26(69)70)36(82)54(93-15)104-44-17(3-59)95-56(38(84)49(44)91-14-28(73)74)105-45-18(4-60)94-55(37(83)48(45)90-13-27(71)72)103-43-16(2-58)92-53(35(81)46(43)88-11-25(67)68)101-41-21(7-87-10-24(65)66)97-51(33(79)30(41)76)99-39-19(5-85-8-22(61)62)96-50(32(78)29(39)75)100-40-20(6-86-9-23(63)64)98-52(102-42)34(80)31(40)77/h15-21,29-60,75-84H,1-14H2,(H,61,62)(H,63,64)(H,65,66)(H,67,68)(H,69,70)(H,71,72)(H,73,74)/t15-,16-,17-,18-,19-,20-,21-,29-,30-,31-,32-,33-,34-,35-,36-,37-,38-,39-,40-,41-,42-,43-,44-,45-,46-,47-,48-,49-,50-,51-,52-,53-,54-,55-,56-/m1/s1InChI KeyCUJVBAPGYBSBHJ-YWBSARSQSA-NSMILESC(C1C2C(C(C(O1)OC3C(OC(C(C3OCC(=O)O)O)OC4C(OC(C(C4OCC(=O)O)O)OC5C(OC(C(C5OCC(=O)O)O)OC6C(OC(C(C6O)O)OC7C(OC(C(C7O)O)OC8C(OC(O2)C(C8O)O)COCC(=O)O)COCC(=O)O)COCC(=O)O)CO)CO)CO)O)OCC(=O)O)O
