Definition
-
DPPH, also known as 2,2-diphenyl-1-picrylhydrazyl, is a synthetic compound that is widely used in the field of chemistry as a free radical scavenger and antioxidant. It is a dark purple-colored crystalline compound that is stable under normal conditions.
In chemical terms, DPPH is classified as a stable free radical due to its unpaired electrons. It has a molecular formula of C18H12N5O6 and a molecular weight of 394.32 g/mol. DPPH is often used in various laboratory assays to determine the antioxidant capacity of different substances or compounds.
When DPPH is exposed to a reducing agent or an antioxidant substance, it undergoes a chemical reaction where the purple color of DPPH fades, indicating the scavenging of the radical by the tested substance. This reaction is widely utilized in antioxidant activity assays such as DPPH radical scavenging assay. The antioxidant capacity of a substance is determined by measuring the degree of discoloration or the decrease in absorbance of purple DPPH solution.
DPPH is a popular compound in research due to its simplicity and reliability in the assessment of antioxidants present in natural products, foods, and pharmaceuticals. Its use provides a quantitative estimate of the antioxidant activity of a substance, indicating its potential for scavenging free radicals and minimizing oxidative stress.
