Ethereal Glycoconjugated Azodyes (GADs): A New Group of Water‐Soluble, Naturalised Dyes

This report deals with azodyes naturalised through glycoconjugation with a very common saccharide – lactose – and with its galactose and glucose components. The conjugation takes place through a bifunctional linker, here a terminal dibromoalkane, so the final products are very stable diether derivatives of the starting dyes. These transformations produce naturalised dyes – indeed, water‐soluble and multipurpose – that are able to dye different materials without addition of chemical additives such as surface agents.(© Wiley‐VCH Verlag GmbH & Co.
