Description

19-Iodocholesterol is a halogenated derivative of cholesterol, a key sterol in biological systems. This compound serves as a crucial biochemical tool and synthetic intermediate, valued for its iodine atom which facilitates radiolabeling and structural modification. It is primarily utilized by researchers and manufacturers in the pharmaceutical, life sciences, and fine chemical sectors for applications in tracer studies, metabolic pathway analysis, and the synthesis of more complex steroid-based molecules.

Application

• Biochemical Research & Tracer Studies: Acts as a precursor for radiolabeled cholesterol analogs (e.g., using I-125) to study cholesterol metabolism, absorption, and localization in biological systems.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel steroid-based drug candidates and diagnostic agents.
• Metabolic Pathway Analysis: Used to investigate sterol biosynthesis and metabolic disorders in academic and industrial research settings.
• Reference Standard: Employed as a high-purity analytical standard in chromatography (HPLC, GC) for method development and quality control in steroid analysis.
• Material Science: Potential use in the development of specialized liquid crystals or advanced organic materials due to its steroidal backbone.
