N-Phenethylurea Chemical Properties,Usage,Production

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion.Many N-nitroso compounds are carcinogens. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise the (±)-urea from H2O (m 112-113o) or EtOH. The picrate has m 113-115o (from H2O) [Spica Gazzetta 9 567 1879, Shapiro et al. J Am Chem Soc 81 2224 1959]. [Beilstein 12 1099, 12 III 2423, 12 IV 2470.]
