title: Spectrophotometric determinations of isoniazid with metol and vanadate, ferricyanide or iron(III).
abstract: Three spectrophotometric methods for the assay of isoniazid with metol and vanadate, iron(III) or ferricyanide have been developed. The common excipients in pharmaceutical preparations do not interfere. The recovery and precision are similar to those of the official B.P. method.
