- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- 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 melting point of 3,4-dichlorophenyl isocyanate was determined in a series of experimental studies to be in the range of 41 °C to 43 °C.
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.

Daubert, T.E. et. al, 1989
The melting point of 3,4-dichlorophenyl isocyanate is 43°C.
In all of these study reports, no information on the corresponding atmospheric pressure is reported.
The mean value of the determined melting points was chosen as key-value for chemical saftey assessment.
