Description of key information

The test item decomposed at approximately 230 ± 0.5°C (503 ± 0.5 K) at 102.18 kPa. As the test item decomposed, no value for boiling temperature could be determined by differential scanning calorimetry, using ASTM E537-86, designed to be compatible with Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

Key value for chemical safety assessment

Additional information

A reliability rating of 1 was assigned to the key study, according to the criteria of Klimisch, 1997 as the study was conducted in accordance with recognised guidelines and GLP.

Supporting information is also available from 2 Safety data sheets (Gelest, 2003 & Crompton, 2000). The results contained in these were a boiling point of 175 ºC at a reduced pressure of 1 mmHg and a decomposition temperature of approximately 230 °C respectively.

A reliability rating of 4 was assigned as the safety data sheets are secondary source information.
