Description

(1R)-7β-Ethyl-1,2,3,4,4A,4Bα,5,6,7,8,8Aα,9,10,10Aα-Tetradecahydro-1,4Aβ,7-Trimethyl-1α-Phenanthrenecarboxylic Acid Methyl Ester is a high-purity, stereochemically defined steroidal intermediate of significant importance in advanced organic synthesis. This compound matters as a critical chiral building block for the development of complex pharmaceutical molecules and fine chemicals, offering a rigid, functionalized backbone. It is primarily needed by research institutions and industrial manufacturers engaged in the synthesis of novel steroids, hormone analogs, and other bioactive compounds requiring precise stereochemical control.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the multi-step synthesis of novel steroidal drugs and active pharmaceutical ingredients (APIs).
• Fine Chemical Synthesis: Used as a sophisticated building block for constructing complex molecular architectures in research and development.
• Steroid Chemistry Research: Enables the study of structure-activity relationships (SAR) and the development of new hormone analogs or receptor modulators.
• Process Chemistry Development: Serves as a standard or intermediate in scaling up synthetic routes for commercial production.
• Biochemical Research: Potential use as a probe or standard in metabolic pathway studies involving steroidal frameworks.
