Description

Cholesterol Valerate (CAS No. 7726-03-6), with the molecular formula C₃₂H₅₄O₂, is a high-purity cholesteryl ester widely utilized in biochemical and pharmaceutical research. This compound, also known as Cholesteryl pentanoate or Valeric Acid Cholesterol Ester, is a critical reagent for studying lipid metabolism, membrane biophysics, and lipoprotein structure-function relationships. Our Cholesterol Valerate is synthesized under stringent quality control measures to ensure ≥95% purity (HPLC detection at 205 nm), making it ideal for sensitive analytical applications such as LC-MS, NMR, and enzymatic assays. The product is supplied as a stable white to off-white crystalline solid, soluble in organic solvents like chloroform, methanol, and DMSO. It is particularly valuable for calibrating lipidomic workflows, investigating atherosclerosis models, and developing cholesterol-based drug delivery systems. Each batch undergoes rigorous characterization to guarantee consistency in melting point (∼90-94°C) and spectral properties (FTIR, ¹H/¹³C NMR compliant). Store desiccated at -20°C to maintain long-term stability.
