STRUCTURE SEARCH

Structure Search

Draw or input SMILES first, then search and filter results on the left panel.

Similarity threshold 0~10.5000

Supported Structure Inputs

Enter SMILES, InChI, or draw a molecule in the editor to locate exact or related chemical records.

  • SMILES and canonical SMILES
  • InChI and Mol structure files
  • Edit a result structure and search again

Search Modes

Choose exact, similarity, or substructure search depending on the sourcing and R&D question.

  • Exact match for target compound checks
  • Similarity search for alternatives
  • Substructure search for shared scaffolds

Result Filters

Refine results by keyword, CAS, and similarity score, then open product detail pages when records are available.

  • CAS and MDL identifiers
  • IUPAC, SMILES, and supplier fields
  • Structure previews and detail links
