Antifebrin

Antifebrin, or ACETANILID, introduced in 1886 as a febrifuge, the cheapness of which, combined with its rapidity of action and its non-poisonous nature, have brought it rapidly into favour as a substitute for quinine. A white colourless powder, with burning taste, it is almost insoluble in cold water, though readily soluble in alcohol. It is derived from anilin, to which it is closely allied, its chemical formula being $C\_6H\_5NHC\_2H\_3O$.
