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 separation by

In the course of the estimation of the impurity profile of ethynodiol diacetate, in addition to common impurities such as norethisterone acetate, ethynodiol-3-acetate and alpha-ethynodiol diacetate, two unknown impurities were detected by analytical

The thermal decompositions of lithium, sodium, potassium, rubidium and caesium formates were investigated by a complex dynamic thermoanalytical method. The ratio of the products in reactions resulting in alkali metal carbonates and oxalates depended

The thermal behaviour of tetrahydroperparine (THP) and its derivatives with various acids has been investigated. The acid is liberated from the formate derivative basically in two steps, while the other aliphatic acids are released quantitatively bef

The thermal and thermo-electrical behaviour and properties, as well as the type structure and appearance of the liquid crystalline phases of the sodium salts of saturated, non-branching fatty acids were investigated. The measurements were carried out

The electrical conductivity (EC) and differential thermal analysis (DTA) curves of MnHgI4 complexes (M = Ag1+, Cu1+, Hg22+, Tl1+ and Pb2+) and HgI2 and AgI are reported. The EC—DTA curves were obtained for each of the following heating—cooling mo
