Description

3β-Trimethylsilyloxylanosta-9(11),24-Diene CAS NO 55538-95-9 is a high-purity, semi-synthetic steroidal derivative, specifically a silyl-protected lanostane intermediate. This compound is of significant value in advanced organic synthesis and pharmaceutical research, serving as a crucial precursor for the development of novel therapeutic agents. It is primarily required by research institutions, pharmaceutical development laboratories, and fine chemical manufacturers focused on steroid chemistry, anti-inflammatory drug discovery, and metabolic pathway studies.

Application

• Pharmaceutical Intermediate: Key synthetic precursor for the development of novel steroidal drugs and bioactive molecules targeting inflammation and metabolic disorders.
• Organic Synthesis Building Block: Used in complex multi-step syntheses to introduce the protected lanostane core structure, enabling further functionalization.
• Biochemical Research: Employed in academic and industrial research to study enzyme inhibition, receptor binding, and the structure-activity relationships (SAR) of steroidal compounds.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in pharmaceutical analysis (HPLC, LC-MS).
• Process Chemistry: Utilized in scale-up and optimization studies for the production of target active pharmaceutical ingredients (APIs) in a GMP environment.
