Type

Table entries are sorted according to reliability of the data, listing the most reliable type first: L) literature review, M) measured, V) VP/AS = vapor pressure/aqueous solubility, R) recalculation, T) thermodynamical calculation, X) original paper not available, C) citation, Q) QSPR, E) estimate, ?) unknown, W) wrong. See Section 3.1 of Sander (2015) for further details.

Notes

38) Calculated based on the method by Meylan and Howard (1991).
107) Data taken from the supplement.
108) Calculated using the EPI Suite (v4.0) method.
109) Calculated using the SPARC (v4.2) method.
110) Calculated using the COSMOtherm (v2.1) method.
111) Calculated using the ABSOLV (ADMEBoxes v4.1) method.
