By heating phenolphthalein and hydrazine hydrate in diethylene glycol, two kinds of crystalline product, (A) of m. p. 266-267° and (B) of m. p. 255-256°, were obtained. (B) alone was obtained when phenolphthalein was allowed to stand with hydrazine hydrate at ordinary temperature or when warm hydrazine hydrate was added. The structure of these two substances was determined through the preparation of their derivatives and from their infrared and ultraviolet absorption spectra.
