6α-chloro Testosterone 17-O-Acetate is an intermediate for the synthesis of 6α-Chloro Testosterone (C386003), which is a derivative of Testosterone, the principal hormone of the testes, produced by the interstitial cells. Major circulating androgen; converted by 5α-reductase in androgen-dependent target tissues to 5α-dehydrotestosterone which is required for normal male sexual differentiation.
