Abstract
The present invention relates to novel dextran derivatives having a plurality of carboxylic acid groups positioned upon intermediate glucose or glucopyranose units of the dextran polymer, and substances formed therefrom by complexing or chelation with colloidal ferric hydroxide to produce stable products of low intravenous toxicity and containing a relatively high iron content. It further relates to a process for producing said polycarboxylic acid compounds as well as the ferric hydroxide complexes described.
