<i>Tautobase</i>: An Open Tautomer Database

Abstract

There has been decades of research on determining and predicting acid dissociation constants (pKa) and the tautomer ratios both experimentally and theoretically. However, the lack of an extensive publicly available database of measured tautomeric ratios in water and nonaqueous solvents poses a challenge for the researchers interested in theoretical studies related to tautomers. Hereby, we present Tautobase, to date and to the best of our knowledge, the first extensive open-source tautomer database of measured and estimated tautomer ratios mainly in water, containing 1680 unique tautomer pairs.
