Description:

Estra-5(10),9(11)-dien-3-one, 17-methyl-17-(1-oxopropyl)-, cyclic 3-(1,2-ethanediyl acetal), (17β)-, with CAS number 42982-45-6, is a synthetic steroid compound characterized by its complex molecular structure, which includes a steroid backbone with specific functional groups. This compound features a ketone group at the 3-position and a methyl group at the 17-position, along with a cyclic acetal structure that contributes to its stability and reactivity. The presence of the ethylene bridge in the acetal enhances its chemical properties, potentially influencing its biological activity. As a derivative of estradiol, it may exhibit hormonal activity, making it of interest in pharmaceutical applications, particularly in the field of endocrinology. Its unique structural features may also affect its solubility, melting point, and interaction with biological receptors. However, detailed studies are necessary to fully understand its pharmacokinetics and pharmacodynamics.
