Estimation of Impurity Profiles of Drugs and Related Materials. 12. Isolation and Identification of an Isomeric Impurity in Danazol

·doi:10.1023/a:1016201630774

We report on a new isomeric impurity of danazol. This impurity designated as isodanazol was detected by reversed-phase high-performance liquid chromatography (HPLC) and thin-layer chromatography (TLC). Its structure was determined after sep…

Estimation of impurity profiles in drugs and related materials. Part 11 — the role of chromatographic and spectroscopic methods in the estimation of side-reactions in drug syntheses

·doi:10.1016/0731-7085(93)80107-c

Impurities in drugs are classified on the basis of the types of side-reactions in drug syntheses resulting in their formation. This is shown by summarizing the authors' earlier results in the field of impurity profiling of 19-nor-steroids, …
