(E)-4-Hydroxytamoxifen is an active metabolite of the tamoxifen. This metabolite acts as a selective estrogen receptor modulator, binding to the estrogen receptor and blocking the effects of estrogen in breast tissue. (E)-4-Hydroxytamoxifen is being studied for its potential use in hormone-related conditions. Its ability to modulate estrogen receptor activity makes it important in the study of hormone-related conditions.
