Did they ever create the bridge from Wikipedia to Wikidata? I remember hearing talk about it as a way of helping the lack of data. The problem I had with Wikidata a couple years ago was that it was usually an incomplete subset of Wikipedia's infoboxes.
You get a lot more useful data, like the dipole moment and solubility (kinda important for a solvent like Xylene), and tons of other properties that Wikidata just doesn't have. All in the infobox.
It's weird that they don't just copy the Wikipedia infobox for the chemicals in Wikidata. It's already there and organized. And frequently cited.
Maybe it's more useful for other fields, but I can't think of a good use I'd get from the chemical section of Wikidata over the databases it cites or Wikipedia itself...
I'm not that familiar with the subject, but I did read[1] that Wikidata's adoption has been slowed by the fact that triples can only be used on one page (per localisation). There is some support for using it with infoboxes though[2].
Checking again for m-xylene, https://m.wikidata.org/wiki/Q3234708
You get physical property data and citations.
Now compare that to the chem infobox in wikipedia: https://en.m.wikipedia.org/wiki/M-Xylene
