After I sent this I began to wonder if it made any sense and also if anyone had actually done it. However, the name Tylenol is derived from the chemical name

N-acetyl-para-aminophenol So, perhaps.

I haven’t thought about chemistry at this level since 1968, so it’s not obvious to me why this substitution would produce similar results and merit the same name. Does anyone have a simple explanation? At first blush, when the developing agent is changed, you can’t sensibly call the developer by the same name.
