title: The application of ferrihydroxamic complexes to photocolorimetric determination of drugs. Part 2: Quantitative determination of calcium pangamate (vitamin B15) and its calcium gluconate mixtures.
abstract: A quantitative method for calcium pangamate (Vitamin B15) and calcium gluconate determination, separately and in mixture, is proposed on the basis of the ferric hydroxamate procedure. The method may also be applied to the determination separately and in mixture, is proposed on the basis of the ferric of both preparations in mixture with various other substances which are not converted into lactone from in acid medium, and which the ferric hydroxamate procedure fails to develop.
