I believe paracetamol and Tylenol are brand names.

Not really, paracetamol is international name of chemical compound.

		No, N-(4-hydroxyphenyl)acetamide is the IUPAC name. Paracetamol & acetaminophen are "generic" names for it when used as a drug. Tylenol, Panadol, and quite a few other brand names are used worldwide¹. The International Chemical Identifier is InChI=1S/C8H9NO2/c1-6(10)9-7-2-4-8(11)5-3-7/h2-5,11H,1H3,(H,9,10). ¹https://en.wikipedia.org/wiki/List_of_paracetamol_brand_name...
