Description

16Alpha-Ethyl-21-Hydroxy-19-Norpregn-4-Ene-3,20-Dione 21-Laurate is a high-purity steroid derivative, specifically a laurate ester of a 19-norprogesterone analog. This compound is valued for its role as a critical pharmaceutical intermediate in the synthesis of advanced steroid-based active pharmaceutical ingredients (APIs). It is primarily required by research institutions and manufacturers in the pharmaceutical and biotechnology sectors for the development of novel therapeutic agents.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the multi-step synthesis of specialized steroid hormones and related APIs.
• Steroid Research & Development: Used in academic and industrial R&D laboratories for studying structure-activity relationships (SAR) and developing new drug candidates.
• Process Chemistry: Employed in scale-up and optimization of synthetic routes for complex steroid molecules in pilot plants and manufacturing facilities.
• Reference Standard: Can be utilized as a high-purity analytical reference standard for quality control and method validation in pharmaceutical analysis.
