Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

A summary of runs 1 -3 is shown below:

Run 1  Run 2  Run 3 
Correlation:  -0.9993 -0.9912 -0.999
Slope:  -6192 -4720 -4706
Intercept:  17.26 13.16 13.08
Log Vpat 25°C:  -3.51 -2.67 -2.71
Vp (Pa) at 25°C:  3.1 × 10-4  2.2 × 10-3  2.0 × 10-3 

Runs 2 and 3 were in good agreement and higher than the initial run. The vapour pressure was therefore calculated as the mean of the latter two runs and was determined to be 2.1 × 10-3 Pa at 25°C.

A visual assessment of the sample following testing confirmed that the test item had not undergone significant change.

Applicant's summary and conclusion

Conclusions:
The vapour pressure of 2-Bromo-6-(4-toluoyl)pyridine was found to be 2.1 × 10⁻³ Pa at 25°C.
