2amino6oxo

2amino6oxo is a shorthand descriptor encountered in chemical informatics to denote a molecular motif in which an amino group is attached at position 2 and a keto (oxo) substituent is attached at position 6 of a heterocyclic or related ring system. It is not an official IUPAC name or a discrete chemical by itself, but rather a substructure annotation used in databases, annotations, and substructure searches to indicate a particular functional pattern.

In practice, 2amino6oxo can refer to a class of compounds where the 2-amino and 6-oxo functionalities are part of a ring framework, which may be six-membered or bicyclic, or embedded within a larger scaffold. The exact identity, properties, and reactivity of such compounds depend on the complete ring system and any additional substituents. Therefore, the motif alone does not define a unique substance.

Substructure search and cheminformatics workflows sometimes encode this motif in patterns such as SMILES or SMARTS to identify candidate molecules in libraries. The interpretation of the motif can vary by software tool, and precise matching requires a defined context, including the ring size and connectivity surrounding the 2- and 6-positions.

As a fragmentary descriptor, 2amino6oxo typically appears as part of a larger chemical description rather than a standalone compound. For any specific substance associated with this motif, full structural information and validated identifiers (IUPAC name, CAS number, InChI) are necessary to determine its properties and applications.
