Spectrophotometric Determination of Piperazine in Pharmaceutical Preparations
View through CrossRef
Abstract
A solution of piperazine or its salts is heated with 2,6-dichloroquinonechlorimide, and the color produced is measured at 525 nm to obtain the concentration of piperazine. The color developed obeys Beer’s law in the concentration range of 6.4–51.2 μg piperazine/ml. The results of the proposed method agree with those of the official methods within ± 1.0% for piperazine and its salts and ± 2.0% for formulations. The method is rapid and precise and gives reproducible results. It is suitable for the analytical control of piperazine or its salts and their formulations.
