EF 3.1 publishes trifluoromethoxymethane twice here, both rows in kilograms and both carrying 421-14-7: as `Methyl trifluoromethyl ether`, with ten synonyms -- `Trifluoromethoxymethane`, `CF3OCH3`, `Methane, trifluoromethoxy-`, `Methyl perfluoromethyl ether` -- EF's ILCD note, and no characterisation; and as `HFE-143a`, the refrigerant designation, with no synonyms and Climate change 616.0. Whether that is one substance is answered by the number both rows carry: PubChem's CID 73947 is 421-14-7, trifluoromethoxymethane, and its synonyms include `Methyl trifluoromethyl ether` and `Trifluoromethyl methyl ether`. One substance under a chemical name and an industry code, which is the case this file was made for. `HFE-143a` survives for the ordinary reason: it is the row that holds the factor, and the merge gives it to a row that had none. Retiring the named row loses nothing it carries, because the synonyms and the ILCD note are on the flow object the two share and the substance goes on being published as `Methyl Trifluoromethyl Ether`. The named row's seven soil and water rows are uncontested and stay; so does `HFE-143a`'s own row in the lower stratosphere, which the named row does not reach. Until this ruling the collision stood, and a standing collision is what a source row cannot be placed onto: Stepwise 2006's `Ether, 1,1,1-trifluoromethyl methyl-, HFE-143a` 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.

One substance under a chemical name and an industry code, which is the case this file was made for. `HFE-143a` survives for the ordinary reason: it is the row that holds the factor, and the merge gives it to a row that had none. Retiring the named row loses nothing it carries, because the synonyms and the ILCD note are on the flow object the two share and the substance goes on being published as `Methyl Trifluoromethyl Ether`. The named row's seven soil and water rows are uncontested and stay; so does `HFE-143a`'s own row in the lower stratosphere, which the named row does not reach. Until this ruling the collision stood, and a standing collision is what a source row cannot be placed onto: Stepwise 2006's `Ether, 1,1,1-trifluoromethyl methyl-, HFE-143a` 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.

| 293,367 | pipeline.collision_decisions | owl_deprecated | — | yes | merged onto 9308ce4c-e251-11e6-bf01-fe55135034f3 by curator ruling: Unspecified air, kilograms. EF 3.1 publishes trifluoromethoxymethane twice here, both rows in kilograms and both carrying 421-14-7: as `Methyl trifluoromethyl ether`, with ten synonyms -- `Trifluoromethoxymethane`, `CF3OCH3`, `Methane, trifluoromethoxy-`, `Methyl perfluoromethyl ether` -- EF's ILCD note, and no characterisation; and as `HFE-143a`, the refrigerant designation, with no synonyms and Climate change 616.0. Whether that is one substance is answered by the number both rows carry: PubChem's CID 73947 is 421-14-7, trifluoromethoxymethane, and its synonyms include `Methyl trifluoromethyl ether` and `Trifluoromethyl methyl ether`.
