Water Sol from Kow (WSKOW v1.42) Results:



Water Sol: 318.5 mg/L


SMILES : n(ccc(c1)CCCc(cccc2)c2)c1

CHEM  : Pyridine, 4-(3-phenylpropyl)-

MOL FOR: C14 H15 N1

MOL WT : 197.28

---------------------------------- WSKOW v1.42 Results ------------------------

Log Kow (estimated) : 4.04

Log Kow (experimental): not available from database

Log Kow used by Water solubility estimates: 4.04


Equation Used to Make Water Sol estimate:

Log S (mol/L) = 0.796 - 0.854 log Kow - 0.00728 MW + Correction

(used when Melting Point NOT available)


Correction(s):        Value
