Description

Cholesteryl Oleyl Ether CAS NO 66106-91-0 is a high-purity, non-ionic sterol derivative widely used as a key intermediate and functional additive in advanced chemical synthesis. This compound is valued for its unique amphiphilic properties derived from its cholesterol backbone and oleyl chain, making it an essential component for modifying surface characteristics and enhancing formulation stability. It is primarily sought after by manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries for applications ranging from liposome formulation to the production of liquid crystal materials and bio-lubricants.

Application

• Liposome and Nanoparticle Formulation: Acts as a structural lipid component to enhance membrane stability and control drug release profiles in pharmaceutical delivery systems.
• Cosmetic and Personal Care Ingredients: Serves as an emollient and skin-conditioning agent in high-end creams, lotions, and anti-aging serums.
• Liquid Crystal and Display Technology: Used as a chiral dopant or additive to fine-tune the electro-optical properties of liquid crystal mixtures.
• Biomedical Research: Employed as a fluorescent probe precursor or a membrane mimic in biochemical and biophysical studies.
• Specialty Lubricants and Additives: Functions as a friction modifier and viscosity index improver in high-performance synthetic lubricants.
• Chemical Synthesis Intermediate: Provides a versatile sterol scaffold for the synthesis of more complex bioactive molecules and surfactants.

Quality Control

Our Cholesteryl Oleyl Ether is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting all critical quality attributes are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider packaging under an inert gas such as nitrogen or argon.
