Description
The rhodaminyl moiety is located at C(6). The product is highly hygroscopic and is 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. (2-hydroxy)propylation is random, but almost exclusively on the secondary hydroxyl rim. The material is water soluble, it dissolves in methanol, DMF, DMSO but it precipitates in acetone.
