Description of key information
No boiling of OS 1600 was observed below 250°C, the temperature at which reaction and/or decomposition started. Test substance has no boiling temperature. The boiling point of MPKO, the main hydrolysis product of OS1600 was determined to be 172°C
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 172 °C
Additional information
Key study: The boiling point test was performed on OS-1600 in accordance with OECD Guideline 103 and EU Method A.2. No boiling of OS 1600 was observed below 250 ºC, the temperature at which reaction and/or decomposition started. Test substance has no boiling temperature.
Supporting study: The boiling temperature of the analogue substance MPKO was determined using a Q100 difference scanning carolimeter. The boiling point was 172°C at an atmospheric pressure of ca. 101.7 kPa.
