CAS number 58-19-5 corresponds to drostanolone, also known as dromostanolone. This compound is a potent androgenic and anabolic steroid that belongs to the family of dihydrotestosterone (DHT) derivatives.
Drostanolone is characterized by its unique chemical structure, featuring a 2α-methyl group addition to the DHT molecule. This modification enhances its anabolic properties while reducing its androgenic effects compared to testosterone. The molecular formula of drostanolone is C20H32O2, with a molecular weight of 304.47 g/mol.
In the medical field, drostanolone has been used in cancer chemotherapy, particularly for treating breast cancer in postmenopausal women. It was marketed under the brand name Drolban by Eli Lilly. However, its use in clinical settings has declined over time due to the development of newer treatment options.
Among bodybuilders and athletes, drostanolone is valued for its ability to promote lean muscle growth, enhance strength, and improve physical performance. It's often used during cutting cycles due to its non-aromatizing nature, meaning it doesn't convert to estrogen, which helps maintain a dry and hard muscular appearance.
The synthesis of drostanolone involves a complex process, typically starting from a precursor compound and involving hydrogenation and purification steps. The final product is a colorless solid with specific chemical properties, including a melting point between 145-147°C.
It's important to note that the use of drostanolone, like other anabolic steroids, is controlled in many countries and banned in most sporting competitions. Its use without medical supervision can lead to various side effects and health risks. As with all performance-enhancing substances, careful consideration and professional guidance are essential before contemplating its use.
