The IUPAC name of Epiandrosterone is (3S,5S,8R,9S,10S,13S,14S)-3-hydroxy-10,13-dimethyl-1,2,3,4,5,6,7,8,9,11,12,14,15,16-tetradecahydrocyclopenta[a]phenanthren-17-one. With the CAS registry number 481-29-8, it is also named as 3beta-Hydroxyetioallocholan-17-one. The product's categories are pharmaceutical intermediates; steroids; 17-ketosteroids; biochemistry; hydroxyketosteroids. It is white to off-white crystalline powder whih is used for steroid hormone drug. It was first isolated in 1931, by Adolf Friedrich Johann Butenandt and Kurt Tscherning. Additionally, Epiandrosterone should be sealed in the container that the container is placed in the cool and dry aera. Furthermore, people ahould not breathe dust and avoid contact with skin and eyes.
The other characteristics of this product can be summarized as: (1)ACD/LogP: 3.75; (2)# of Rule of 5 Violations: 0; (3)#H bond acceptors: 2; (4)#H bond donors: 1; (5)#Freely Rotating Bonds: 1; (6)Index of Refraction: 1.536; (7)Molar Refractivity: 83.49 cm3; (8)Molar Volume: 267.6 cm3; (9)Polarizability: 33.1×10-24 cm3; (10)Surface Tension: 41.1 dyne/cm; (11)Enthalpy of Vaporization: 76.93 kJ/mol; (12)Vapour Pressure: 1.5E-08 mmHg at 25°C; (13)Tautomer Count: 2; (14)Exact Mass: 290.22458; (15)MonoIsotopic Mass: 290.22458; (16)Topological Polar Surface Area: 37.3; (17)Heavy Atom Count: 21; (18)Complexity: 459.
Preparation of Epiandrosterone: It can be converted from the natural steroids androstanediol via 17β-hydroxysteroid dehydrogenase or from androstanedione via 3β-hydroxysteroid dehydrogenase. And it is also naturally obtained by the enzyme 5-alpha reductase from the adrenal hormone dehydroepiandrosterone (DHEA).
People can use the following data to convert to the molecule structure.
