Derivative Type: dl-Form
Properties: Crystals from water, mp 235-236°. Slightly sol in water, much less sol in methanol and ethanol. Practically insol in the higher alcohols, in dioxane, ethyl acetate, ether, benzene, chloroform, glacial acetic acid, pyridine, Cellosolve. Sol in dil acids or bases and may be recovered from these solns by adjusting the pH so that it is just acid to bromcresol green. uv max: 282 nm (log e 4.23).
