Abstract
The three geometrical isomers of dinestrol diacetate may be determined quantitatively and simultaneously by gas-liquid chromatography using 3% SE- 30 on Gas-Chrom Z as stationary phase; they can also be determined in the presence of indenestrol diacetate and pinacolone 4,4′-bis( p-hydroxyphenyl)-3-hexanone diacetate. The gas-liquid chromatographic method may be used in analyses of industrial residues and in purity determination of pharmaceutical grade dienestrol and dienestrol diacetate. An auxiliary thin-layer chromatographic procedure is also described.
