Abstract

Molecular compounds of ascorbic acid or iso-ascorbic acid and quinidine are prepared by melting the components together, or by dissolving them in a solvent and precipitating the product, or by double decomposition of their salts in solution. The products contain either one or two molecular proportions of the acid to one molecular proportion of the base. For preserving purposes, an excess of the acid may be used. The products, which are readily water-soluble, are useful therapeutically. Their preparation, of which examples are given, may be effected in an atmosphere of an indifferent gas such as nitrogen. Specification 469,335 is referred to.
