IUPACrecognized

IUPACrecognized is a term used in scientific writing and database curation to indicate that a chemical term, name, or resource adheres to the naming and nomenclature standards set by the International Union of Pure and Applied Chemistry (IUPAC). The term functions as an informal descriptor rather than an official designation from IUPAC. When a resource is described as IUPACrecognized, it typically means that it uses systematic or preferred IUPAC names (PINs) where available, applies correct stereochemical descriptors, and follows IUPAC recommendations for functional groups, substituent ordering, and parent structures.

Usage and scope: It is commonly used in chemical databases, dictionaries, educational materials, and software that implements naming rules. It can cover organic and inorganic compounds, polymers, and biomolecules, provided the entry applies appropriate IUPAC conventions and avoids common name ambiguities.

Criteria: The entry should present names that are the result of IUPAC-compliant naming, indicate PINs, provide unambiguous formulas, use correct locants, and indicate stereochemistry when relevant.

Limitations: The term is informal; not a formal stamp. IUPAC recommendations evolve over time, and some resources may apply partial or evolving interpretations.

Relation to IUPAC: IUPAC publishes official guidelines; IUPACrecognized resources reflect these guidelines but do not imply official endorsement or certification.
