Review THERMO SCIENTIFIC Free Radical

Thermo Scientific 044150.md 2,6-DiPhenyl-1-Picrylhydrazyl (DPPH) Radical Solution, 95%

Description:

The Thermo Scientific 044150.md 2,6-DiPhenyl-1-Picrylhydrazyl (DPPH) Radical Solution is a high-performance antioxidant reagent designed for the quantitative determination of antioxidant activity in various samples. This solution comes in a dark brown colored bottle, which is a characteristic of DPPH due to the presence of the stable free radical DPPH.

DPPH is a stable, purple-colored nitroxyl radical, which readily accepts electrons or hydrogen atoms from antioxidants. The antioxidant capacity of a sample is determined by the ability to reduce the DPPH radical to its colorless diphenylpicrylhydrazine form. The decrease in absorbance at 517 nm is directly proportional to the antioxidant activity of the sample.

This Thermo Scientific DPPH solution is supplied at a concentration of 95%, based on the absorbance at 517 nm against a blank solution. It is recommended for use within 3 months after opening, due to the gradual loss of radical activity over time. To maintain the stability of the solution, it should be stored in a cool, dark place, away from light and oxygen.

The DPPH solution is suitable for use in various applications, including the determination of antioxidant capacity in foods, beverages, cosmetics, pharmaceuticals, and biological samples. It is also useful for quality control and research purposes in the fields of food science, pharmacology, and biochemistry.

To prepare a working standard solution, dilute the DPPH solution with an appropriate solvent, such as methanol or ethanol. The optimal concentration of the working solution may vary depending on the specific sample and the sensitivity of the analytical method.

For precise and accurate results, it is important to follow the recommended protocols for sample preparation, dilution, and data analysis. The Thermo Scientific DPPH solution, along with the proper equipment and analytical techniques, enables researchers and analysts to assess the antioxidant activity of various samples with confidence and accuracy.
