ZINC is a free, curated collection of commercially available chemical compounds. It is designed specifically for virtual screening, providing researchers with the structural data needed to dock millions of molecules against biological targets. Contains over 230 million purchasable compounds. Accessibility: Open-access for academic and commercial use. Ensure the salts have been stripped if your

SMILES are easily tokenized for neural networks.

ZINC files are often provided as .gz archives. Use zcat or gunzip to process them without fully extracting if disk space is tight. Select the subsets you need (e
