description: The Sigma-Aldrich Chemical Structure Search API enables substructure, exact structure, and
  similarity searches against the Sigma-Aldrich chemical catalog using SMILES, InChI, or molecular formula
  notation. Supports configuring similarity thresholds and returning ranked results for drug discovery,
  materials research, and synthetic chemistry workflows.
