Description

Cholesterol NF

Cholesterol NF is a high-purity sterol used in pharmaceutical, biomedical, and research applications as a membrane component, formulation aid, and structural lipid. Compliant with National Formulary (NF) standards, it is widely utilized in liposomal formulations, emulsions, and advanced drug delivery systems.
Cholesterol is chemically designated as Cholest-5-en-3β-ol. It appears as a white to off-white crystalline powder or flakes that are practically insoluble in water and soluble in organic solvents such as ethanol and chloroform. Its rigid sterol structure plays a critical role in modulating membrane fluidity and stability.
In pharmaceutical and research applications, Cholesterol NF is used in:
• Liposomal and nanoparticle drug delivery systems
• Stabilization of lipid bilayers and vesicular formulations
• Emulsion and microemulsion systems
• Injectable and parenteral lipid-based formulations
• Research involving membrane biology and lipid interactions
• Development of controlled-release and targeted delivery platforms
Cholesterol NF functions by integrating into lipid bilayers and regulating membrane permeability, fluidity, and mechanical strength. Its presence enhances the structural integrity and stability of liposomes and other lipid-based delivery systems.
CarboMer supplies Cholesterol NF with defined assay, impurity profile, and physicochemical characteristics suitable for regulated pharmaceutical manufacturing and advanced formulation development.
The material meets NF monograph specifications and is appropriate for controlled pharmaceutical production environments.
The material is packaged in sealed, moisture-resistant, tamper-evident containers and protected from excessive light to preserve stability and handling quality. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and full traceability.
Each batch is tested for identity, assay, melting range, impurity profile, and water content where applicable. Technical support is available to assist with formulation development, lipid system design, and stability optimization.
As with all CarboMer supplied lipid and sterol materials, Cholesterol NF is supported by dependable global supply, rigorous quality systems, and expert technical guidance to ensure consistent and reliable performance across pharmaceutical and research applications.
