Controlled Vocabulary
| Allowed Value | Details |
|---|---|
| Canonical SMILES | Simplified Molecular-Input Line-Entry System (SMILES) computed from chemical structure devoid of isotopic and stereochemical information |
| IUPAC Name | Chemical name computed from chemical structure that uses International Union of Pure and Applied Chemistry (IUPAC) nomenclature standards |
| InChI | International Chemical Identifier (InChI) computed from chemical structure using the International Union of Pure and Applied Chemistry (IUPAC) standard |
| InChI Key | International Chemical Identifier hash (InChIKey) computed from chemical structure using the International Union of Pure and Applied Chemistry (IUPAC) standard |
| Isomeric SMILES | Simplified Molecular-Input Line-Entry System (SMILES) computed from chemical structure containing isotopic and stereochemical information. SMILES written with isotopic and chiral specifications are collectively known as isomeric SMILES |
