Evidence (3)

DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 77298-66-9 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). Curator can promote to a CHEBI primary if/when CHEBI adds the term.

DATABASE_MATCH via CHEBI via PubChem (pubchem-xref)

Parent class identified via pubchem-xref; matched_via='pubchem CID 5391149'

DATABASE_MATCH via MIM curation (#326)

mapping_quality NARROW_MATCH -> SYNONYM_MATCH. The recorded molecular_formula is identical to CHEBI:94071's, and a 'parent' with an identical formula is not a parent — BACKFILL_PARENT_CHEBI found the term via a PubChem xref and filed it as one. Identity confirmed by InChIKey (NUGPQONICGTVNA-UHFFFAOYSA-N): the record's own cas_rn, written from CultureBotHT compounds_to_cas.csv at creation and so independent of this mapping, resolves in PubChem to the same key ChEBI records for the term. ontology_id is unchanged.
