PharmacopæIas and Formularies: The British Pharmacopæia, 1948: The Assay of Alkaloidal Salts

Abstract

In the control of the purity of alkaloidal salts and similar compounds the question arises whether it is necessary to estimate the physiologically active base, or if it is sufficient to determine the other part of the compound molecule. In general, the estimation of the active base gives the best control of purity, but the methods are often laborious and troublesome. It is often difficult to find a good method for the estimation of the active substance, whereas a simple and quick method for the estimation of the other part of the molecule is readily available.
