  Curator note
  Extending the demonstrated sodium-perchlorate role to the dissolved monohydrate is a chemical inference about perchlorate supply. The paper does not identify the monohydrate reagent or establish solid-form identity.
Metabolic context
Dissolved perchlorate acceptor for Dechlorosoma suillum PS and Dechloromonas agitata CKB under the studied anoxic, acetate-fed conditions.

DATABASE_MATCH via CultureBotHT

Imported from CultureBotHT. CAS-RN 7791-07-3 present, but no CHEBI entry exists (checked OAK CHEBI sqlite + PubChem CID synonyms). FEBA/Hans80 panels: Hans80metals, FEBA_stress. Used in 2 CultureBot media; samples: ALP defined perchlorate, ALP_defined_perchlorate. Curator can promote to a CHEBI primary if/when CHEBI adds the term.

DATABASE_MATCH via CHEBI via OLS (stem-substring)

Parent class identified via stem-substring; matched_via='Sodium perchlorate monohydrate'

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:132103 ('sodium perchlorate') — 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.
