Rafik Karaman

Dear Esmaeel,

I have used a program named "Solubility Prediction in Any Solvent " which is contained in the following link:

http://showme.physics.drexel.edu/onsc/models/multisolvent.php?solutename=Benzoic+acid&solutesmiles=OC(%3DO)C1%3DCC%3DCC%3DC1&solvent=benzene&solventsmiles=c1ccccc1&sdm=0.01&sdc=2.28

The predicted solubility (M) in DMSO was calculated to be 11.8.

You can use the program: type the compound name and the Solute SMILES and run the calculation.

The Solute SMILES for mandilic acid is: C1=CC=C(C=C1)C(C(=O)O)O

Hoping this will be helpful,

Rafik
