Description

4-Androsten-3Beta,17Beta-Diol-11-One CAS NO 14485-67-7 is a high-purity steroid intermediate, specifically an 11-oxygenated derivative of androstenediol. This compound is valued for its role as a critical building block 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 production of corticosteroids and other specialized therapeutic agents.

Application

• Pharmaceutical Intermediate: A key precursor in the multi-step synthesis of corticosteroid drugs, including anti-inflammatory and immunosuppressive agents.
• Research & Development: Used in academic and industrial laboratories for studying steroid metabolism, receptor interactions, and developing novel therapeutic compounds.
• Fine Chemical Synthesis: Serves as a specialized starting material for custom synthesis and contract manufacturing of high-value steroid derivatives.
• Reference Standard: Can be utilized as an analytical standard in quality control laboratories for method development and impurity profiling.
