CAS 145-13-1: Pregn-5-en-20-one, 3-hydroxy-, (3β)-
Description:Pregn-5-en-20-one, 3-hydroxy-, (3β)-, commonly known as progesterone, is a steroid hormone that plays a crucial role in the menstrual cycle, pregnancy, and embryogenesis in humans and other species. It is characterized by its steroid structure, which consists of four fused carbon rings, and features a hydroxyl group at the 3-position, contributing to its biological activity. Progesterone is a white crystalline solid that is slightly soluble in water but more soluble in organic solvents such as ethanol and chloroform. It has a melting point that typically falls within a specific range, indicating its solid state at room temperature. As a key hormone, progesterone is involved in regulating various physiological processes, including the preparation of the endometrium for potential implantation of an embryo and the maintenance of pregnancy. Its synthesis occurs primarily in the ovaries, placenta, and adrenal glands. Due to its significant biological functions, progesterone is also utilized in various medical applications, including hormone replacement therapy and contraceptive formulations.
