OECD QSAR Toolbox

Name: OECD QSAR Toolbox
License: Proprietaer

The OECD's tool for chemicals evaluation — substance search (CAS/EC/SMILES), chemical properties (with Klimisch reliability scores) and GHS classification. Status: stub until an ECHA licence and a local Toolbox server instance are configured (QSAR_TOOLBOX_BASE_URL + QSAR_TOOLBOX_TOKEN). Tracked in #2448.
