PubChem's CID 206000 is 163702-05-4 and lists `HFE-7200`, `NOVEC HFE 7200` and `HFE-569sf2 (7200)` among its synonyms, so the designation and the IPCC code are two names for one substance. The factor sets are equal, which makes this the carbon tetrachloride case (#105) rather than the ordinary one: deduplication's sort would fall through to the identifier and decide nothing about the chemistry. What decides is what the rows carry and what reaches them. `HFE-569sf2` survives: it holds the registry number's whole synonym set and EF's note, it is the row EF publishes in soil and water as well as air, and one of its synonyms -- `Ether, nonafluorobutane ethyl-` -- is the head of Stepwise 2006's own name for the row this ruling unblocks. `n-HFE-7200` carries the same number and the same factor and nothing else. What is not settled here is EF's separate `HFE-7200` row, which carries 163702-06-5 and no factor. PubChem's CID 205999 is that number and it is ethyl perfluoroisobutyl ether -- a different molecule, the branched isomer -- so that row and `i-HFE-7200` are #19's question and not this one. Until this ruling the collision stood: Stepwise 2006's `Ether, nonafluorobutane ethyl-, HFE569sf2 (HFE-7200)` was tied between the two rows (`tied-elementary-candidates`) and published nowhere, on the four-list build of 29 August 2026 one of only two unplaced rows in 22,005.

EF 3.1 publishes 1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane twice here, both rows in kilograms, both carrying 163702-05-4 and both carrying Climate change 60.7: as `n-HFE-7200`, with no synonyms and four air contexts and nothing else; and as `HFE-569sf2`, with twelve synonyms -- `1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane`, `HFE-7200`, `Ethyl Nonafluorobutyl Ether`, `Ether, nonafluorobutane ethyl-` -- EF's ILCD note, and eleven contexts across air, soil and water. PubChem's CID 206000 is 163702-05-4 and lists `HFE-7200`, `NOVEC HFE 7200` and `HFE-569sf2 (7200)` among its synonyms, so the designation and the IPCC code are two names for one substance. The factor sets are equal, which makes this the carbon tetrachloride case (#105) rather than the ordinary one: deduplication's sort would fall through to the identifier and decide nothing about the chemistry. What decides is what the rows carry and what reaches them. `HFE-569sf2` survives: it holds the registry number's whole synonym set and EF's note, it is the row EF publishes in soil and water as well as air, and one of its synonyms -- `Ether, nonafluorobutane ethyl-` -- is the head of Stepwise 2006's own name for the row this ruling unblocks. `n-HFE-7200` carries the same number and the same factor and nothing else. What is not settled here is EF's separate `HFE-7200` row, which carries 163702-06-5 and no factor. PubChem's CID 205999 is that number and it is ethyl perfluoroisobutyl ether -- a different molecule, the branched isomer -- so that row and `i-HFE-7200` are #19's question and not this one. Until this ruling the collision stood: Stepwise 2006's `Ether, nonafluorobutane ethyl-, HFE569sf2 (HFE-7200)` was tied between the two rows (`tied-elementary-candidates`) and published nowhere, on the four-list build of 29 August 2026 one of only two unplaced rows in 22,005.
