Evidence (3)

DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 2451-01-6 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 anchor_cas_hydrate_records

Terpene hydrate is a hydrate/salt with its own CAS and no exact ChEBI term; anchored to the parent CHEBI:134806 'terpin' by narrowMatch per MAPPING_SEMANTICS.md Section 3 step 2. CAS 2451-01-6 is terpin hydrate; the label 'Terpene' is a misspelling of terpin

DATABASE_MATCH via MIM curation (#342)

mapping_quality NARROW_MATCH -> CLOSE_MATCH, predicate skos:narrowMatch -> skos:closeMatch. narrowMatch asserts this record is *narrower in meaning* than CHEBI:134806 ('terpin') — a subsumption ChEBI itself denies: it files hydrates under CHEBI:35505 'hydrate', never under the anhydrous compound, which is not an ancestor even transitively. A hydrate is a distinct substance containing the anhydrous form, not a specialization of it. closeMatch claims similarity without subsumption. The ontology_id and the record's own identifier are unchanged.
