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 melting point of 1,2,4-Trichlorobenzene was determined in a series of experimental studies to be in the range of 16 °C to 17.4 °C. Most melting points were reported between 17 °C and 17.4 °C. The melting point of 17 °C was chosen as key value for chemical safety assessment (reported by several individual references).
