Create trustworthy, searchable, and compliant chemical datasets. This hands-on module teaches structure standardization (salts/tautomers/protonation/valence) , ID generation (SMILES/InChI) , duplicate detection & merge rules, and registration workflows (business rules, lots/batches, audit trails) that power discovery, QSAR, and regulatory reporting. You will ship reproducible QC/QA pipelines aligned to FAIR principles.
