Description

11β-Hydroxy-5β-Pregnane-3,20-Dione is a high-purity steroid intermediate of significant importance in pharmaceutical synthesis. This compound serves as a crucial building block for the production of more complex steroid-based active pharmaceutical ingredients (APIs). It is primarily required by research institutions and manufacturers in the pharmaceutical and biotechnology sectors engaged in the development and production of corticosteroid and other hormonal therapies.

Application

• Pharmaceutical Intermediate: A key synthetic precursor in the manufacture of corticosteroid APIs and other steroid hormones.
• Biochemical Research: Used as a reference standard or substrate in metabolic pathway studies and enzyme inhibition assays.
• Process Development: Employed in the research and scale-up of novel synthetic routes for steroid-based drugs.
• Analytical Standard: Serves as a high-purity standard for quality control and analytical method development (e.g., HPLC, GC-MS) in pharmaceutical labs.
