Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Based on the available data on its physical and chemical properties,2-hydroxy-4-(methylthio)butyronitrile (HMTBN) is acolourless/yellow liquid with a strong odour,it hasafreezingpoint below –50°C at standard pressureand a relative density of1,11 at 20°C(+/- 0,5°C).
HMTBNdecomposes into 3-(methylthio)propanal and hydrogen cyanide when heating between 215°C and 310°Cat standard pressure. The stability of HMTBN is also link to the pH. The pH need to be acid (pH<5) in order to avoid the degradation in AMTP and the polycondensation of cyanure.
HMTBN is considered as alow volatility substancewith a vapour pressure of approximately0,075 Pa at 25°C.
It is consideredvery solublein water based on a water solubility between110 g/L, and to have alow potential for bioaccumulationbased on a predictedlogKow value of -0.62.
Besides, HMTBN has been shown to benon flammable based on its flash point above to 92°Cand it has aauto-ignition temperature of270°C.Based on its chemical structure, HMTBN isnot expected to be explosive nor to have oxidising properties.
