BETA W7 MCT is the first reactive cyclodextrin derivative manufactured
on an industrial scale. It has a monochlorotriazinyl group as a react
ive anchor well known from many reactive dyes. This derivative is able
to form stable covalent bonds with nucleophilic groups and can be eas
ily prepared in water in an effective one pot synthesis from cyanuric
chloride and beta-cyclodextrin in a yield of approx. 90% based on the
triazinyl group. The optimised degree of substitution of DS = 0.4 per
anhydroglucose ensures a good complexation capacity even when this der
ivative is fixed to surfaces like textiles. This cyclodextrin derivati
ve containing 2-3 reactive groups in the ring can be used as building
block for new CD derivatives, as a crosslinking agent or as an excelle
nt material for surface modification.
