Properties: Crystals from methanol. Dec 240°. Moderately sol in water. More sol in alcohol, butanol, isobutanol. Insol in amyl alcohol, octyl alcohol, benzene, chlorobenzene, chloroform. Destroyed upon boiling the aq soln, more rapidly in the presence of alkali. At room temp it is destroyed in alkaline soln. Reacts with ketones in aq alkaline soln to produce a greenish-blue fluorescence; on acidification the fluorescence changes to blue, and is intensified by heating.
