List Version Source flow Name there Why this flow
EF 3.1 d8b989c5-c92a-4c1d-8c2b-532b2d0a562b Boron trifluoride The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 cdca4dea-89cb-5733-9350-eb2a24a2799b Boron Trifluoride The CAS numbers are the same (7637-07-2); both name the same compartment.
