Determination of the active ingredient content of technical and formulated dinobuton, dinoseb, dinoterb and DNOC by high-performance liquid chromatography, spectrophotometry and gas-liquid chromatography
Abstract
A reversed-phase high-performance liquid chromatographic (HPLC) method is described for the determination of the active ingredient content of technical and formulated dinobuton, dinoseb, dinoterb and DNOC. The results obtained by HPLC are compared with those obtained using gas-liquid chromatography for dinoterb and spectrophotometry for the other compounds.
