:(17β)-17-(Acetyloxy)-4-chloroestr-4-en-3-one
Description:
The chemical substance known as (17β)-17-(Acetyloxy)-4-chloroestr-4-en-3-one, with the CAS number 1164-99-4, is a synthetic derivative of the steroid hormone estrone. It features a chloro group at the 4-position and an acetoxy group at the 17β position, which contributes to its biological activity. This compound is classified as a progestin, meaning it can mimic the effects of progesterone in the body, and is often utilized in hormonal therapies and contraceptives. Its structural modifications enhance its potency and selectivity for progesterone receptors. The presence of the chloro substituent can also influence its metabolic stability and pharmacokinetics. In terms of physical properties, it is typically a solid at room temperature and may exhibit low solubility in water but higher solubility in organic solvents. As with many steroid derivatives, it may have implications in both therapeutic applications and potential side effects, necessitating careful consideration in clinical use.
