Justification for type of information:
Due to insufficient reporting of the experimental details, this study was rated with a Klimisch score of 4 (‘not assignable’). As none of the available studies can serve as a key study with a sufficiently detailed reporting justifying a Klimisch score of 1 or 2 for the given endpoint, several independent sources were used in a weight of evidence approach. The combined data from handbooks or collection of data provide experimental values in a similar range, supporting the reliability of the result.

Description of key information

The individual study reports (data from handbooks or collection of data) show some deficiencies with respect to the comprehensiveness of the experimental details. Therefore, a reliability of 1 or 2 and thus adequacy as key study was not assignable for any of the individual studies. Consequently, the studies were assigned a Klimisch score of 4 (according to guidance document R.4, ‘not assignable: studies or data […] which are only listed in short abstracts or secondary literature (books, reviews, etc.)). As the individual studies report values are in a similar range, collectively, these studies can be used to conclude on this endpoint and to satisfy the information requirement.


The boiling point of 4-nitrotoluene was determined in a series of experimental studies and found to be in the range of  237.7 °C - 239 °C:


Booth, G. (Ullmann's), 2005: 4-Nitrotoluene has a boiling point of 238.3 °C at 101 kPa.


Dugal, M. (Kirk-Othmer), 2005: 4-Nitrotoluene has a boiling point of 238.5 °C at 101 kPa.


ROEMPP, 2009: 4-Nitrotoluene has a boiling point of 238 °C at 1013 hPa.


Merck, 2006: 4-Nitrotoluene has a boiling point of 238 °C (the corresponding atmospheric pressure was not reported).


Hommel/Verschueren, 1997/1996: 4-Nitrotoluene has a boiling point of 238 °C at 1013 hPa.


Lide/MITI, 2001/1992: 4-Nitrotoluene has a boiling point of 238.3 °C at 1013 hPa.


Auer/Sax, 1988: 4-Nitrotoluene has a boiling point of 238.3 °C at 1013 hPa.


Beilstein, 2002: 4-Nitrotoluene has a boiling point in the range of of 237.7 °C - 239 °C at 1013 hPa.


 


The boiling point of 238 °C at 1013 hPa was chosen as key value for chemical safety assessment (independently reported in several studies).
