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 density of 1,2,4-trichlorobenzene was determined in a series of experimental studies and is 1.45 g/cm³ to 1.46 g/cm³ in the temperature range from 20 °C to 25 °C.
The experiments by Jungfleisch show a decrease in density with an increase in temperature (10 °C - 196 °C; 1.47 g/cm³ - 1.24 g/cm³). The density of 1.46 g/cm³ (determined at room temperature: 20-25 °C) was chosen as key value for chemical safety assessment.
