Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- May 1992
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. However, some informations are missing in the experimental report. Purity is specified in the report, and isomers composition is available from the notifier. Therefore validation applies, but with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- Directive 84/449/EEC
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 19 June 1990. Signed on 5 October 1990.
- Type of method:
- distillation method
- Specific details on test material used for the study:
- Storage condition of test material: metal can, under refrigeration at 2-8°C in the dark.
- Key result
- Boiling pt.:
- 316.8 - 339.8 °C
- Atm. press.:
- 988.6 mBar
- Decomposition:
- ambiguous
- Executive summary:
The boiling range of the test substance was measured under GLP according to EU A2 guideline, distillation method.
Two runs were performed. The range retained was the mean of the initial boiling point values and the dry point values.
The boiling range of the test substance is 316.8 - 339.8°C. The colour change may indicate a chemical change upon heating.

Description of key information
Boiling range (multi-isomers) = 316.8 to 339.8°C (under 988.6 mbar)
The colour of the substance changes upon heating (turns yellow).
Key value for chemical safety assessment
Additional information
A reliable study, conducted according to a recognized EC method and under GLP, is available. Despite restrictions due to missing information in the report, it is considered as a key study. The change of state occurs within a 23°C-interval, which can be explained by the multi-isomers nature of the substance. As the result is expressed as a range, and because of possible decomposition, no key value is retained.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
