10081-39-7 - Introduction
2,6-diphenyl-4-(2,4, 6-triphenyl-1-pyridinium) phenolic acid, also known as DPPH(2,6-diphenyl-4-(2,4,6-triphenyl-1-pyridinyl)phenol). The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: DPPH is a dark purple crystalline solid.
-Solubility: It is soluble in organic solvents (such as ethanol, dimethylbenzene, dichloromethane), but insoluble in water.
-Oxidative: DPPH is a highly stable free radical that can be reduced by oxidants to colorless products.
-Stability: It is relatively stable to light and heat.
Use:
-Chemical analysis: DPPH can be used as a redox indicator to determine the reduction properties of substances.
-Antioxidant: DPPH is a commonly used natural antioxidant that can be used to detect and evaluate antioxidant properties in foods, drugs and cosmetics.
-Spectroscopy: DPPH can also be used in infrared spectroscopy and fluorescence spectroscopy.
Preparation Method:
The preparation method of DPPH is more complicated and usually needs to be synthesized by chemical reaction. One common method of preparation is the reaction of 2,6-diphenyl -4-cresol with 2,4, 6-triphenylpyridine to give 2,6-diphenyl -4-(2,4, 6-triphenyl-1-pyridinium) benzolic acid.
Safety Information:
- DPPH is relatively safe for human health under general conditions of use.
-It is a non-flammable solid, but contact with combustibles and high temperatures should be avoided.
-During operation, you should wear appropriate personal protective equipment, such as laboratory gloves and glasses, to avoid contact with skin and eyes.
-When performing large-scale synthesis or experimental operations, it is recommended to perform it in a well-ventilated laboratory, and take additional safety measures as needed.
