Used as a key intermediate in the semi-synthesis of paclitaxel (Taxol), a potent anticancer drug. It serves as a starting material for chemical modification to introduce functional groups necessary for biological activity. Due to its structural similarity to the taxane core, it enables more efficient production of paclitaxel and related analogs, especially when natural sources are limited. This role is critical in pharmaceutical development for treating ovarian, breast, and lung cancers.
