Cellobiosan (also known as 1,6-Anhydro-beta-cellobiose) is an anhydrosugar formed from the elimination of one water molecule from cellobiose. This water is lost from one of the glucose sugars in the disaccharide and a 1,6 glycosidic linkage is formed within that sugar.

After levoglucosan, cellobiosan is the most abundantly produced product from the pyrolysis of cellulose. As a result of this there has been much work on finding ways in which it can be valorised or further converted to other products. For instance, cellobiosan can be hydrolysed to glucose using acids or, like levoglucosan, it can be directly fermented using some micro-organisms.
