ABSTRACT:
Sodium N-acetylneuraminate trihydrate herein provided is represented by the following formula: ##STR1## The sodium N-acetylneuraminate trihydrate can be prepared, for instance, according to a method which comprises the steps of: dissolving sodium N-acetylneuraminate in water or in a mixture of water and an organic solvent; allowing the resulting solution to stand; precipitating and separating the resulting crystals of sodium N-acetylneuraminate.trihydrate; and then drying the separated crystals. The sodium N-acetylneuraminate trihydrate has very low hygroscopicity and hence can be handled without any difficulty in the form of powder.
