Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The vapour pressure of MITC (methyl isothiocyanate) was measured / extrapolated using different sources; we found ca 3 kPa at 50°C.
Key value for chemical safety assessment
- Vapour pressure:
- 3 000 Pa
- at the temperature of:
- 25 °C
Additional information
A bibliographic study was made using different sources:
- According to Bauer (1935), vapour pressure of MITC (methyl isothiocyanate) at 10°C equals 12.5 torr (i.e 1.66 kPa), at 50°C 68.5 torr (i.e. 9.13 kPa)
- Using the equation given in the CHEMSAFE data base, vapour pressure of MITC at 35.8°C is 4.89 kPa and 118.82°C 103.43 kPa.
- According to Degussa (1981), MITC (methyl isothiocyanate) has got the following vapour pressure : 5.9997 kPa at 40°C - 9.133 kPa at 50°C and 53.329 kPa at 97.8°C.
Finally a study was made by Hundington for MLPC on behalf of MLPC in 2010 according to the Swiloboff method (OECD 104),
and the value of 3 kPa was found for and 25°C. All the values are in accordanceInformation on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
