Molecules in this set

* have a molecular weight of fewer than 1500 Daltons,
* not possess counter ions,
* only contain the elements C, H, O, N, P, S, F, Cl, Br, I, Se and B,
* not contain isotopes of Hydrogens (D, T),
* have 3–40 bonds,
* not contain any charged groups including zwitterionic forms,
* only contain implicit hydrogens, except in functional groups,
* have less than 40 SMILES characters,
* no stereochemistry is allowed.

The original dataset from Decimer was imported and randomly sampled. 516x516 sized images were generated using RDKit.
