Description

Cholesteryl 11-14 Eicosadienoate is a high-purity, synthetic cholesterol ester derivative, specifically the ester of cholesterol and a conjugated eicosadienoic acid. This compound is valued for its role as a critical intermediate and reference standard in advanced lipid research and pharmaceutical development. It is primarily utilized by research institutions and manufacturers in the life sciences, pharmaceutical, and specialty chemical sectors for applications requiring precise lipid structures.

Application

• Lipidomics Research: Serves as a critical analytical standard for the identification and quantification of complex lipid species in biological samples using techniques like LC-MS.
• Pharmaceutical Intermediates: Acts as a key building block in the synthesis of novel therapeutic agents targeting lipid metabolism and membrane function.
• Biomembrane Studies: Used in model membrane systems (e.g., liposomes, bilayers) to study the effects of specific cholesterol esters on membrane fluidity, permeability, and protein interactions.
• Reference Material: Employed as a certified reference material (CRM) for quality control and method validation in analytical laboratories.
• Biochemical Reagent: Utilized in enzymatic assays and studies related to cholesterol ester metabolism, including the activity of enzymes like LCAT (lecithin–cholesterol acyltransferase).
• Specialty Chemical Synthesis: Functions as a precursor for the development of advanced materials, surfactants, or other specialty esters with unique properties.

Quality Control

Our Cholesteryl 11-14 Eicosadienoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the sealed container to reach room temperature before opening to minimize moisture condensation. Keep away from strong oxidizing agents.
