Description

2,19-(Methyleneoxy)Androst-4-Ene-3,17-Dione CAS NO 136182-63-3 is a high-purity, synthetic steroid derivative characterized by its unique 2,19-methyleneoxy bridge. This compound is a critical pharmaceutical intermediate valued for its role in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs). It is primarily required by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in the development and production of specialized therapeutic agents.

Application

• Pharmaceutical Intermediate: A key building block in the multi-step synthesis of novel steroid-based drugs and hormonal therapies.
• Research & Development: Used in academic and industrial research for studying steroid biochemistry, receptor interactions, and metabolic pathways.
• Process Chemistry: Serves as a precursor in the development and scale-up of manufacturing processes for advanced steroid compounds.
• Reference Standard: Employed as a high-purity analytical standard for quality control and method validation in pharmaceutical analysis.
• Biochemical Tool: Utilized in biochemical assays to investigate enzyme inhibition, particularly those involved in steroidogenesis.
