1,2-dichloro-3-nitrobenzene

Vapour pressure

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

vapour pressure

Type of information:

experimental study

Adequacy of study:

weight of evidence

Reliability:

4 (not assignable)

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.

Principles of method if other than guideline:

secondary peer reviewed source, valid collection of data

GLP compliance:

not specified

Type of method:

other: no data

Temp.:

20 °C

Remarks on result:

other: vapour pressure negligible

Vapour pressure, Pa at 20 °C: negligible

Conclusions:

The vapour pressure of the substance at 20 °C is negligible as it is a solid.

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 in a similar range, collectively, these studies can be used to conclude on this endpoint and to satisfy the information requirement.

The vapour pressure of 1,2-dichloro-3-nitrobenzene was determined in a series of experimental studies and found to be <2 Pa (0.673 Pa) at 25 °C:
