Usage

General Description

"13-ethyl-17alpha-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one butyrate" refers to a synthetic compound that's primarily used for its hormonal properties. Like many similar substances, it's derived from progesterone, a naturally occurring steroid hormone. It is complex due to its series of carbon, hydrogen, and oxygen atoms, arranged in a very specific molecular structure. 13-ethyl-17alpha-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one butyrate is used in reproductive medicine, specifically in oral contraceptives and is classified as a hormonal synthetic steroid. Its butyrate refers to its ester or salt form of butyric acid.
