Colorimetric Analysis of Procaine Hydrochloride

Journal of Pharmaceutical Sciences, 1974
Abstract A colorimetric assay procedure was developed for the quantitative analysis of procaine hydrochloride. The method is based on the interaction of procaine hydrochloride with p -dimethyla minocinnamaldehyde in the presence of trichloroacetic acid in absolute methanol to form a red Schiff base which can be quantitated spectrophotometrically at ...

Hydrazones of Isoniazid for Colorimetric Analysis

Journal of Pharmaceutical Sciences, 1977
Two sensitive color reactions of isoniazid are described. They are based on the formation of hydrazone Schiff bases when isoniazid is reacted with 4-nitrobenzaldehyde or pyridoxal. Linear curves were obtained with both reagents when absorbance values were plotted against concentrations.

Colorimetric Analysis of Hexachlorophene in Topical Formulations

Journal of Pharmaceutical Sciences, 1975
The commonly used 4-aminoantipyrine dye formation procedure for hexachlorophene analysis in topical formulations was modified to overcome interference due to other components. Bar soaps and nonemulsion formulations are analyzed directly, employing a chloroform back-extraction stage of the dye prior to quantitation.
