This document summarizes an open notebook science application for predicting melting points, solubility, and recommending recrystallization solvents. The application uses open data and open source software to make predictions about melting points and solubility that can then be used to select optimal recrystallization solvents. It provides open web services and models for properties like melting point and solubility that were developed using open data and are intended to increase transparency and reproducibility in chemistry.
