Mutarotation 8-sulfate

CHEMICAL PROPERTIES stable in air stable under ordinary conditions of use and storage hazardous polymerization will not occur hydrolyzes to glucose and fructose by dilute acids and by invertase, a yeast enzyme optical rotation falls and is negative upon completion of hydrolysis does not reduce Fehling s solution (consists of two solutions, one of copper sulfate, the other of alkaline tartrate), forms an osazone, or show mutarotation fermentable, but resists bacterial decomposition when in high concentrations. FP (NA) LFL/UFL (NA) AT (NA) MEC (45g/cm ). 

The hydrazones and osazones rarely have sharp melting points, and disparities in reported values are often encountered. Moreover, optical rotations are frequently difficult to determine because of slow, complex mutarotations. Confirmation of the identity through a comparison of X-ray patterns or through other derivatives is desirable. The osotriazoles (Chapter VIII) prepared from the osazones by the reaction of copper sulfate generally have properties quite suitable for qualitative analyses. Isolation of the more-soluble osotriazoles is facilitated by adsorption on and elution from activated carbon (29a),...
