DATABASE_MATCH
via Edison LITERATURE deep research
Edison literature research (research/ingredients/NaH2PO4H2O-edison-literature.md) identifies this as sodium dihydrogen phosphate MONOHYDRATE, CAS 10049-21-5. CHEBI:37585 'sodium dihydrogenphosphate' is the ANHYDROUS form (its own dbxref is CAS 7558-80-7), so the two are distinct substances -- MAPPING_SEMANTICS.md Section 3: the hydrate takes its own cas: identifier with a narrowMatch to the anhydrous parent, rather than being folded onto it.

| 2026-05-11T05:36:00Z | mediaingredientmech-agentic-curation LLM | REVIEWED_HYDRATE_AMBIGUITY | UNMAPPED | Reviewed against local CHEBI:37585 mapped records; not merged because the source term is explicit NaH2PO4 monohydrate while the local mapped representatives carry anhydrous sodium dihydrogenphosphate chemistry. |
| 2026-08-06T00:00:00+00:00 | promote_resolved_unmapped | PROMOTED_TO_MAPPED | MAPPED | Promoted UNMAPPED_0028 -> cas:10049-21-5 "sodium dihydrogenphosphate" (NARROW_MATCH); mapping_status UNMAPPED -> MAPPED, SSSOM row added. |
| 2026-09-23T04:49:55.744418+00:00 | claude LLM | MERGED_INTO | REJECTED | Merged into CHEBI:114249 'Sodium phosphate monobasic monohydrate'; occurrences transferred. Tombstoned REJECTED, SSSOM rows dropped. The cas: identity was the Section 3 step 2 fallback on the premise that ChEBI has no monohydrate term; CHEBI:114249 sodium dihydrogenphosphate monohydrate exists, xrefs cas:10049-21-5, and is held by this record: one substance under two identifiers (#312). |
| 2026-09-23T04:53:11.712894+00:00 | claude LLM | CORRECTED | REJECTED | identifier cas:10049-21-5 -> CHEBI:114249 on the merge tombstone, so the merged name is credited to the live record that holds the identifier (Rule K; the #414 Mgcl2x_6_H2o precedent). The 2026-08-06 promotion used the Section 3 step 2 cas: fallback on the premise that ChEBI has no hydrate term. CHEBI:114249 'sodium dihydrogenphosphate monohydrate' (H2O.H2O4P.Na, InChIKey BBMHARZCALWXSL-UHFFFAOYSA-M) exists and xrefs cas:10049-21-5, the very CAS the record was keyed on, and Sodium_phosphate_monobasic_monohydrate already holds it: one substance under two identifiers -> merge (#312). |
