The fluoresceinyl moiety is located at C(6). The unlabeled cyclodextrins contain a single amino moiety attached on the primary hydroxyl rim. The product is hygroscopic.
Description: The fluorophore (5/6 isomeric mixture) is attached on the primary hydroxyl rim of the cyclodextrin, via a chemically stable thioureido group. The fluorophore labeled macrocycle content is ~ 1% w/w. The unlabeled cyclodextrins contain a single amino moiety attached on the primary hydroxyl rim. The amino groups increase the solubility of the polymer if compared to the neutral analogue (CY-FL-2009) and can be a potential place for further modification of the structure. The cooperative interactions of the CD-based polymeric network increase the possibility of solubilization of large substrates, while the fluorescent label makes the compound trackable. The product is highly water soluble.
Applications: Fluorescent microscopy, host-guest complexation, transmembrane processes, pharmaceutical and biological tool.
Storage: at 4 ˚C, protected from direct light and heat in a tightly closed dark glass container.
