Properties: Deep yellow prisms or needles from DMF. Dec gradually above 170°. uv max (methanol): 406, 382, 363, 345 nm. [a]D24 +333° (acidic DMF); -33.6° (0.1N methanolic HCl). Insol in water at pH 6 to 7. Soly at pH 2 or pH 11 in water: about 0.1 mg/ml. Water soly increased by sodium desoxycholate. Soly in DMF 2 to 4 mg/ml; in DMF + HCl: 60 to 80 mg/ml; in DMSO: 30 to 40 mg/ml. Solids and solns appear stable for long periods between pH 4 and 10 when stored at moderate temps out of contact with light and air. LD50 in mice (mg/kg): 88 i.p., 4 i.v. (Keim).
