title: [Assay of organic bases in pharmaceutical preparations using cobalt thiocyanate].
abstract: A rapid and simple colorimetric method is presented for the estimation of organic bases in pharmaceutical preparations. Solid cobalt thiocyanate reagent is used. Many bases form blue coloured ion pairs soluble in dichloromethane.
