You can validate SMILES strings by submitting a batch or single string to check their chemical validity, receiving a per-SMILES validity flag for each input entry.

SMILES validation verifies the syntax and basic chemical validity of molecule representations, preventing downstream errors in cheminformatics pipelines from processing invalid molecular strings.

You can validate multiple SMILES strings at once, as the tool accepts batches and returns a list of dictionaries containing each SMILES string alongside its individual is_valid flag.

SMILES validation checks both syntax and basic chemical validity of the input strings to determine if the molecular representations are structurally sound and correctly formatted.

The best way to filter invalid molecule representations is to run a batch SMILES validation check before property evaluation, using the returned per-item validity flags to exclude invalid entries.

Pipeline errors often occur because invalid SMILES strings are processed without prior validation, making it necessary to verify chemical validity before evaluating candidate molecule properties.
