Thermo Scientific™ β-Carotene is a high-purity carotenoid (≥98.5%, typically 99%) widely used in biological, nutritional, and antioxidant research. Recognized as the most important of the provitamins A, β-carotene is classified as an antioxidant due to its ability to inhibit radical-initiated lipid peroxidation in vitro.
This compound is supplied as a crystalline powder, is air- and light-sensitive, and should be stored in a cool, dark environment. It is soluble in organic solvents such as hexane, DMSO, benzene, chloroform, and cyclohexane, but insoluble in water.
Key Features
- High purity – assay ≥98.5% (typically 99%).
- Provitamin A – precursor to retinol (vitamin A).
- Antioxidant properties – inhibits radical-initiated lipid peroxidation.
- Research-grade quality – RUO (Research Use Only).
- Air & light sensitive – requires protection during handling and storage.
Applications
- Studies on antioxidant mechanisms and free radical biology.
- Nutritional and dietary research into vitamin A precursors.
- Investigations of cancer prevention and oxidative stress.
- Biochemical and pharmaceutical R&D requiring a high-purity carotenoid standard.
