UV spectrophotometry, high-pressure liquid chromatography, and NMR were used to investigate syn-anti isomerization in testosterone 17-enanthate 3-benzilic acid hydrazone. In the crystalline state, the isomeric ratio is dependent on the crystallization solvent. In solutions, including injectable pharmaceutical formulations, an equilibrium isomer mixture (2:1) is formed.
采用紫外分光光度法、高压液相色谱法和核磁共振法研究庚酸睾酮苯甲酰腙的顺反异构化。在结晶状态下,异构体比例取决于结晶溶剂。在溶液中,包括注射用药物制剂中,会形成平衡异构体混合物(2:1)。
