After oral administration to man and animals, it is practically completely absorbed and is excreted largely unchanged via the kidneys. Thiourea WebThiourea is commercially available in Germany with the following typical speci- fications: purity, ≥ 99.0%; water, ≤ 0.30%; ash, ≤ 0.10%; thiocyanate (rhodanide), ≤ 0.15%; other nitrogen-containing compounds, ≤ 0.5%; and iron, ≤ 10 mg/kg. Special grades with higher purity are also available (Mertschenk & Beck, 1995).
