Sugar sulfates optical rotations

Optical rotations have been recorded for most preparations of sugar sulfates but may be of little diagnostic value, since the values for isomeric sugar sulfates are often rather close to one another. In some cases, the values recorded in the literature are too numerous to mention individually, and some arbitrary choice of values for inclusion in Table IV has been necessary. 

Table IV lists most of the sulfates of sugars and their derivatives found in the literature. Where the position of the sulfate group is known with reasonable certainty, this is indicated otherwise, no position is given. Not all of the values of melting points and optical rotations are given for those sulfates that have been prepared a number of times, but the more serious discrepancies have been included. Cyclic sulfates and the chloro-deoxy sulfates, prepared by the action of sulfuryl chloride, have been excluded, since they can be found in a few published papers. ...
