ʻO ka Phenacetin kahi hui kemika me ke ʻano molekala C10H13NO2. He lāʻau analgesic a antipyretic ia i hoʻohana mua ʻia e hoʻēmi i ka ʻeha a hoʻemi i ke kuni. Ma ke ʻano, aia ka phenacetin i kahi mole acetaminophen (paracetamol) me kahi hui ethoxy i hoʻopili ʻia i ke apo benzene. Hoʻokaʻawale kēia hui ethoxy i ka phenacetin mai ka acetaminophen. Ma ke ʻano o nā waiwai kino, ʻo ka phenacetin ka mea maʻamau he paʻa keʻokeʻo keʻokeʻo me ka ʻono iki. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai akā hiki ke hoʻoheheʻe ʻia i loko o ka waiʻona a me nā mea hoʻoheheʻe organik ʻē aʻe.
