Determination of mepyramine, aminophenazone, nialamide and chloroquine using the deltapj method.
Mepyramine maleate, aminophenazone, nialamide and chloroquine phosphate are examples of compounds which do not fulfil the requirements of the delta A method. By the proper choice of polynomial and wavelengths, the deltapj method has been successfully applied to their determination. The mean percentage recoveries were found to be 100.2 +/- 0.8, 99.6 +/- 0.6, 99.1 +/- 1.7 and 100.4 +/- 1.3, respectively.
