The water solubility of thiourea is according the Ullmann`s Encyclopedia
of Industrial Chemistry 13.7 g/ 100g water at 20°C which equates 137
g/l. Thus, thiourea is very soluble.
The water solubility of thiourea was determined at 20°C according the
OECD testguideline A80/6 "Flask method" applying spectralphotometry.
Thiourea is soluble. The water solubility is 90 g/l.
There are four literature sources available for the
weight of evidence.
The results indicate that thiourea is soluble
(1000-10000mg/l) to very soluble in water (> 10000mg/l).
The data on the water solubility of thiourea of the Ullmann handbook is chosen for robust study summary because of the reference temperature of 20 °C instead of 25 °C.
According to four different literature sources thiourea is soluble (1000-10000 mg/l) to very soluble (> 10000mg/l) in water:
- 137.0 g/l at 20 °C (according to Ullmann, 1995)
- 90 g/l at 20 °C (according to Korte und Greim, 1981)
