Metacetamol (developmental code name BS-749), also known as 3-hydroxyacetanilide and AMAP, is a non- toxic regioisomer of paracetamol with analgesic and antipyretic properties, but has never been marketed as a drug. [1] [2]
Metacetamol is known to have several polymorphs. [3] Form II is metastable, while form I is stable. [3] Metacetamol polymorph II transforms to form I upon water moisture or direct contact with water and other popular solvents. [3] Metacetamol II form may be obtained on cooling in narrow temperature regime. [4]
