709-19-3 - Introduction
The acid is an organic compound whose chemical formula is C9H8N2O2. The following is a detailed description of its nature, use, preparation and safety information:
Nature:
-Appearance: acid is a white to off-white solid.
-Solubility: Almost insoluble in water, but soluble in organic solvents such as ethanol, acetone and dichloromethane.
-Melting point: about 231-233 ℃.
Use:
Acid is commonly used as a chemical intermediate and has a wide range of applications:
-Drug research: It can be used as a raw material for the synthesis of anti-tumor and anti-fungal drugs.
-Pesticide manufacturing: It can be used as a synthetic intermediate for pesticides.
-Photoelectric materials: can be used in organic light-emitting diodes (OLED) and dye-sensitized solar cells and other fields.
Preparation Method:
A common method for synthesizing acid is to obtain 2-methyl -3H-benzimidazole by reacting 2-methyl aniline and dicyanophosphite, which is further oxidized and carboxylated to obtain the final product acid.
Safety Information:
-the toxicity information of acid is limited, but it may be irritating to the eyes and skin.
-Wear appropriate personal protective equipment such as safety glasses, gloves and protective clothing when used.
-Avoid inhaling the dust and solution of the substance, and avoid direct contact with the skin and eyes.
-For accidental contact, immediately flush the affected area with water and seek medical help.
Please note that the above information is for reference only. The specific preparation method and safe operation should be determined according to the actual situation and the standard operating procedures of the relevant laboratory.
