This was a topic in the Belgian news a couple of days ago. The issue is not as much whether the isopropanol will be used for chemical warfare, nor if it should be regarded dangerous or if it is on a list with restricted substances, but more that these companies would/should have known that exporting it to Syria is a big risk given the current context. It was more of a moral question rather than a 'scientific' one.

Tons of isopropanol were destroyed in Syria by UN workers when trying to destroy all chemical weapons and precursors.*
