It is a member of phenols and a member of acetamides.

Mix 2-Aminophenol , acetic acid and Acetic anhydride (i.e., crystals appear), and then directly heated on the fire until all dissolved, stop heating, cooling, water dilution, precipitation of crystals filtered dry, to 70-80 ℃ of ethanol recrystallization to obtain 2-acetamidophenol.

Store at -20°C

Recrystallise it from water, EtOH or Est aqueous EtOH. [Beilstein 13 H 370, 13 I 113, 13 II 171, 13 III 778.]
