Khoom piav qhia
Phenacetin yog cov tshuaj sib xyaw nrog cov mis molecular C10H13NO2. Nws yog ib qho tshuaj analgesic thiab antipyretic uas yav tas los siv los txo qhov mob thiab txo kub taub hau. Raws li txoj cai, phenacetin muaj ib qho acetaminophen (paracetamol) molecule nrog ib pawg ethoxy txuas rau lub nplhaib benzene. Pawg ethoxy no txawv phenacetin los ntawm acetaminophen. Nyob rau hauv cov nqe lus ntawm lub cev muaj zog, phenacetin feem ntau yog dawb crystalline khoom nrog ib tug me ntsis qab zib saj. Nws yog me ntsis soluble hauv dej tab sis ntau soluble hauv cawv thiab lwm cov kuab tshuaj organic.
Phenacetin tau raug txiav tawm ntau rau kev siv kho mob vim muaj kev txhawj xeeb txog nws txoj kev nyab xeeb, thiab nws txoj kev siv tau raug hloov los ntawm lwm txoj kev nyab xeeb, xws li acetaminophen (paracetamol).
