Where does “methadone” come from?
I appreciate the detailed instructions, but I notice a significant issue: the etymological chain provided traces "diphenyl" → "phenyl" → Ancient Greek → PIE, but the headword is "methadone," which doesn't appear in this chain at all. Methadone's actual etymology involves "methyl" + "amino" + "diphenyl," so the chain you've provided only accounts for the final component. Without a complete chain for methadone itself, I cannot write an accurate one-sentence summary following your rules, as doing so would violate the requirement to "state only what the chain supports" and "do not invent intermediate steps." Could you provide the complete etymological chain for methadone, or clarify if the headword should be "diphenyl" instead?
