Description

Estra-1,3,5(10)-Triene-3,17Beta-Diol Mono(3-Oxohexanoate) is a high-purity steroid derivative, specifically a monoester of estradiol. This compound is a critical advanced intermediate for the synthesis of complex steroid-based pharmaceuticals and active pharmaceutical ingredients (APIs). It is essential for research and development laboratories and production facilities requiring a reliable, high-quality building block for creating potent hormonal agents and other specialized therapeutic compounds.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of steroidal drugs and novel hormonal therapies.
• Active Pharmaceutical Ingredient (API) Development: Used in R&D for creating new estradiol derivatives with modified pharmacokinetic profiles.
• Biochemical Research: Serves as a reference standard or tool compound in endocrinology and hormone receptor studies.
• Veterinary Medicine: Potential use in the development of hormonal treatments for animals.
• Cosmetic Science R&D: Investigated for use in advanced dermal delivery systems for cosmetic actives (subject to regional regulations).
