Description

Cholesteryl Ester Hydroperoxide is a specialized oxidized derivative of cholesterol, serving as a critical intermediate and reference standard in lipid research. Its primary value lies in its role as a biomarker for oxidative stress and lipid peroxidation, enabling the study of cellular damage mechanisms. This compound is essential for researchers and quality control laboratories in the pharmaceutical, nutraceutical, and life science sectors, particularly those focused on cardiovascular disease, aging, and antioxidant efficacy studies.

Application

• Biochemical Research: Used as a key reference standard in studies of lipid peroxidation, oxidative stress, and free radical biology.
• Pharmaceutical Development: Employed in the research and quality control of drugs targeting atherosclerosis, inflammation, and age-related diseases.
• Diagnostic Reagent Manufacturing: Serves as a critical component in the development of diagnostic kits and assays for measuring oxidative damage in biological samples.
• Nutraceutical & Cosmetic Testing: Utilized to evaluate the efficacy of antioxidant compounds in supplements and skincare products.
• Food Science: Applied in research concerning the stability and spoilage of lipid-containing food products.
• Academic Research: A vital tool in university and institutional labs for teaching and investigating advanced topics in biochemistry and cell biology.

Quality Control

Our Cholesteryl Ester Hydroperoxide is produced and handled under strict quality protocols to ensure batch-to-batch consistency and reliability for research applications. Each lot is characterized using advanced analytical techniques, including HPLC and spectroscopic methods, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your regulatory and research documentation needs.

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). The product is easily oxidized and moisture-sensitive; allow the sealed vial to equilibrate to room temperature before opening to minimize condensation and exposure.
