Specification

Oxandrolone is one kind of white or almost white crystalline powder. The IUPAC name of this chemical is (1S,3aS,3bR,5aS,9aS,9bS,11aS)-1-hydroxy-1,9a,11a-trimethyl-2,3,3a,3b,4,5,5a,6,9,9b,10,11-dodecahydroindeno[4,5-h]isochromen-7-one. The product's categories are miscellaneous; biochemistry; steroids. Additionally, Oxandrolone is toxic and flammable. This chemical is odorless and white crystalline powder which is soluble in chloroform, slightly soluble in ethanol, acetone, ether, and very slightly soluble in water. Besides, the Classification Code of Oxandrolone is Anabolic Agents; Androgen; Androgens; Hormone; Hormones; Hormones, Hormone Substitutes, and Hormone Antagonists; Reproductive Effect. The Oxandrolone is male hormone with the major role protein assimilation. It is used in the treatment of high cholesterol and triglyceride disorders. It will produce irritative smoke when buring. So the storage environment should be ventilate, low-temperature and dry. Furthermore, Oxandrolone can be obtained by 5-androstane-1-en-3-17-dione or 17β-Hydroxy-17-α-methyl derivatives.

Physical properties about Oxandrolone are:

Uses of Oxandrolone:
Oxandrolone is a synthetic hormone with anabolic and androgenic properties. It can be used to promote muscle growth and combat involuntary weight loss. It has also been used to treat cases of osteoporosis. Besides, It is a synthetic anabolic steroid derivative of dihydrotestosterone with an oxygen atom replacing the 2 carbon and methylation in the 17 position.
