CAS 2398-99-4: 9-Dehydrotestosterone
Description:9-Dehydrotestosterone, identified by its CAS number 2398-99-4, is a synthetic androgenic steroid derived from testosterone. It is characterized by the absence of a double bond at the C9 position, which distinguishes it from its parent compound. This modification alters its biological activity and potency. The substance exhibits strong androgenic properties, making it relevant in various therapeutic applications, particularly in hormone replacement therapies and conditions associated with androgen deficiency. Its chemical structure includes a steroid backbone, which is typical of androgens, and it interacts with androgen receptors to exert its effects on target tissues. Additionally, 9-Dehydrotestosterone may influence protein synthesis, muscle growth, and secondary sexual characteristics. Due to its potent effects, it is subject to regulation in many countries, particularly in the context of sports and doping regulations. As with other anabolic steroids, potential side effects may include hormonal imbalances and cardiovascular issues, necessitating careful consideration in its use.
