Applicant's summary and conclusion

Conclusions:
VP: 1.13E-6 mm Hg.
The vapour pressure was calculated by EpiSuite's MPBPVP model.
Executive summary:

The vapour pressure was calculated by EpiSuite's MPBPVP model and found to be 1.13E-6 mm Hg.

This corresponds to a vapour pressure of 0.00015 Pa.

Naphtol AS-G is considered to be inside the applicability domain of the EpiSuite MPBPVP model since the following criteria are fulfilled:

- the molecular weight of Naphtol AS-G is within the molecular weight range of the training set

- Naphtol AS-G has a limited number of functional groups

- all functional groups present in Naphtol AS-G are represented in the training set and have a fragment coëfficiënt available.
