6-deoxy-6-[(5/6)-fluoresceinylthioureido]-HPBCD

INQUIRY

Catalog Number	CD-DR64
Description	The fluoresceinyl moiety is located at C(6). The product is highly hygroscopic and dried to constant weight under 100 mbar vacuum at 50 ˚C. The fluorophore (5/6 isomeric mixture) is attached on the primary hydroxyl rim of the cyclodextrin, via a chemically stable thioureido group. Each cyclodextrin ring contains a fluorescent unit. (2-Hydroxy)propylation is random, but almost exclusively on the secondary hydroxyl rim. The material is water soluble, it dissolves in DMF and DMSO, but it precipitates in acetone.
