Description

Butestrol is a synthetic, non-steroidal estrogenic compound. This high-purity chemical intermediate is valued for its specific biological activity and structural properties, making it a critical component in advanced research and synthesis. It is primarily utilized by the pharmaceutical and life science industries for the development and study of hormonal agents and related therapeutic compounds.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of steroidal and hormonal active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard or probe in studies investigating estrogen receptor binding and hormonal pathways.
• Veterinary Medicine: Employed in the development of hormonal treatments for livestock and companion animals.
• Academic & Contract Research: A vital reagent for universities and CROs (Contract Research Organizations) conducting endocrinology and pharmacology research.
• Fine Chemical Synthesis: Utilized in custom synthesis projects requiring a specific estrogenic backbone for novel compound libraries.
