Oestradiol 17-heptanoate(Cas 4956-37-0) Usage
| Description | Oestradiol 17-heptanoate is a synthetic form of the hormone 17β-estradiol, which is one of the three major naturally occurring estrogens in the human body. |
|
Uses |
Estrogen. Oestradiol 17-heptanoate is not a commonly used term, but it appears to be a compound created by esterifying 17β-estradiol with heptanoic acid to create a longer-acting form of the hormone. |

The rate of appearance of estradiol from the estradiol esters was observed to be dependent upon the ester concentration on stratum corneum surface and to follow the order of: diacetate > valerate > heptanoate > cypionate > acetate.
