Properties: Brilliant yellow needles from n-butanol, dec 273-276°. Sublimes 200°/0.1 mm. uv max (methanol): 250, 311, 388 nm (e 6300, 5700, 11,000) (Celmer, Solomons). Sparingly sol in water (210 mg/l); more sol in methanol, ethanol, chloroform, acetone (1% solns in acetone have been prepd), glacial acetic acid, methyl isobutyl ketone. Less sol in ether, benzene, hexane. Stable in acid and neutral solns, decomp in alkaline soln. Effective vs gram-positive and gram-negative bacteria, fungi and ameboid parasites. LD50 in mice (mg/kg): 25 s.c.; 25 orally (Seneca).
