5-Androsten-3β-ol-17-one ethyleneketal(CAT: R065671) is a synthetic steroid derivative, where the 17-one ketone group is protected by forming an ethyleneketal. This modification enhances the stability of the compound and prevents the keto group from participating in unwanted reactions during chemical synthesis or metabolic processes. It is primarily used in the synthesis of more complex steroid compounds, serving as an intermediate in the production of various pharmacologically active steroids. The ethyleneketal group can be selectively removed under acidic conditions, allowing for precise manipulation of the steroid structure during research or drug development. This compound is of particular interest in organic synthesis and the development of steroid-based therapeutics.
