Description of key information
Due to the inherent substance structure of thiourea, it can be assumed that the vapour pressure of thiourea
can be neglected.
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
Due to the inherent substance structure of thiourea, it can be assumed that the vapour pressure of thiourea can be neglected. This assumption is supported by the values given in the technical report "BUA Stoffbericht 179" prepared by Beratergremium für umweltrelevante Altstoffe (BUA) der Gesellschaft Deutscher Chemiker, 1996. The vapour pressure of thiourea (CAS 62 -56 -6) as reported in the "BUA Stoffbericht 179" is 9.975E-08 hPa at 20 °C.
