DL-Estrone, with the CAS number 19973-76-3, is a synthetic form of the naturally occurring hormone estrone, which is a type of estrogen. It is characterized by its steroid structure, specifically a phenolic A-ring and a ketone group at the C-17 position. DL-Estrone is typically a white to off-white crystalline powder that is soluble in organic solvents such as ethanol and chloroform but has limited solubility in water. This compound plays a significant role in various biological processes, particularly in the regulation of the menstrual cycle and reproductive functions. In pharmaceutical applications, DL-Estrone is utilized in hormone replacement therapy and in the treatment of certain conditions related to estrogen deficiency. Its pharmacological effects are mediated through estrogen receptors, influencing gene expression and cellular activity. As with other estrogens, it is important to monitor its use due to potential side effects and contraindications, particularly in individuals with a history of hormone-sensitive conditions.
