Description

[(3S,8S,9S,10R,13R,14S,17R)-10,13-dimethyl-17-[(2R)-6-methylheptan-2-yl]-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl] 4-pyren-1-ylbutanoate is a high-purity, sterol-derived chemical intermediate featuring a pyrene fluorophore. This compound is engineered for advanced research and development, offering a unique molecular scaffold for fluorescence labeling, photophysical studies, and the synthesis of specialized probes. It is a critical material for scientists and manufacturers in the pharmaceutical, life sciences, and advanced materials sectors seeking to develop novel diagnostic tools or functional materials.

Application

• Fluorescent Probe Synthesis: Serves as a key precursor for creating sterol-based fluorescent probes to study membrane dynamics, lipid rafts, and cellular trafficking.
• Photophysical Research: Used as a model compound in research investigating energy transfer, solvatochromism, and the photochemical properties of polycyclic aromatic hydrocarbon (PAH)-steroid conjugates.
• Bioconjugation & Labeling: The reactive ester group enables covalent attachment to biomolecules (e.g., proteins, peptides) for fluorescence labeling applications in assay development.
• Material Science: Acts as a building block for synthesizing organic semiconductors, liquid crystals, or other functional materials where the combination of steroid rigidity and pyrene fluorescence is advantageous.
• Pharmaceutical Intermediate: Utilized in the research and development of novel therapeutic agents, particularly those targeting sterol-related pathways or requiring fluorescent tags for mechanistic studies.
• Analytical Standard: Provides a high-purity reference standard for method development and quality control in analytical laboratories using techniques like HPLC or LC-MS.
