Dehydroepiandrosterone (53-43-0) is used as the main raw material of steroid hormone drugs and contraceptives.
Dehydroepiandrosterone is produced from cholesterol through two cytochrome P450 enzymes. Cholesterol is converted to pregnenolone by the enzyme P450 scc (side chain cleavage); then another enzyme, CYP17A1, converts pregnenolone to 17α-Hydroxypregnenolone and then to DHEA.

Dehydroepiandrosterone (CAS NO.53-43-0) is white fine crystalline powder. It is soluble in benzene, ethanol, ethyl ether, insoluble in chloroform, petroleum ether
is toxic. It is flammable. It will produce stimulate smoke when buring. So the storage environment should be ventilate, low-
temperature and dry.
