Comments: only for reagent and laboratory purposes, not for human use.
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.

Description: 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. Methylation is a random process. The material is freely soluble in water and soluble in organic solvents (CH2Cl2, DMF).

Applications: Chemosensor, fluorescent microscopy, host-guest complexation, femtosecond processes, transmembrane processes, indicator for anticancer drug.

Storage: at 4 ˚C, protected from direct light and heat in a tightly closed dark glass container.
