Description

(3Alpha)-3-Chloro-Cholest-4-Ene CAS NO 13901-10-5 is a high-purity, functionalized steroidal intermediate derived from cholesterol. This compound is valued for its specific halogenation at the 3-alpha position, which makes it a crucial synthon for the targeted synthesis of more complex steroid derivatives and pharmaceutical agents. It is primarily sought by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for use in organic synthesis and process development.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel steroid-based drugs and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used in academic and industrial laboratories to study steroid metabolism, receptor interactions, and enzyme inhibition.
• Agrochemical Development: Serves as a precursor in the research and development of plant growth regulators and other agrochemicals.
• Reference Standard: Employed as a high-purity analytical standard for quality control and method validation in chromatographic analysis.
• Organic Synthesis: Utilized in complex organic transformations to introduce the cholestane skeleton with a reactive chloro-alkene functionality.
• Material Science Research: Investigated as a precursor for liquid crystals or other functional organic materials due to its rigid steroidal core.
