I think the predicate may need depend on the type of thing we're
linking, and on what is being linked. A strong predicate, like
owl:sameAs, requires a (very) strong similarity between concepts...
this is often not the case... mind you, this applies also to the
things being linked... there are enough alternatives, like rdf:seeAlso
as probably one of the least informative predicaties, via
skos:closeMatch and skos:exactMatch ... for chemicals, I have been
involved in work by the Open PHACTS project (now foundation), led by
Alasdair Gray, on "scientific lenses"... I'm biased, but the
(conference) papers are a good read anyway... [eg Q23034460]

Then perhaps umbel:isLike instead of owl:sameAs?

It conveys sameAs but with a hint of uncertainty.

Hi!
Couldn't you use P460 when there is doubt?
https://www.wikidata.org/wiki/Property:P460
P460's type is Item, which means it is relation between two Wikidata items.
External ID is relation between Wikidata item and something outside Wikidata.
