4-AMino-3-Methoxybenzoic acid (Methyl, ethyl) - Introduction
3-Methoxy-4-nitrobenzoic acid is an organic compound with the chemical formula C8H7NO5. The following is a detailed description of its nature, use, formulation and safety information:
Nature:
-Appearance: 3-Methoxy-4-nitrobenzoic acid is an off-white to light yellow crystalline powder.
-Melting point: about 178-182°C.
-Solubility: Slightly soluble in water, soluble in organic solvents such as ethanol, chloroform, dimethyl sulfoxide and dichloromethane.
Use:
- 3-Methoxy-4-nitrobenzoic acid is used as an intermediate in organic synthesis and can be used to synthesize other organic compounds.
-It can also be used as a raw material for organic dyes.
Preparation Method:
- 3-Methoxy-4-nitrobenzoic acid is usually prepared by the reaction of p-methoxy anisole (3-methoxy benzene ether) and nitric acid. The specific synthetic route can be carried out according to the following steps:
1. The p-methoxyanisole reacts with nitric acid under acidic conditions to generate 3-Methoxy-4-nitrobenzoic acid.
2. The product was purified by distillation to obtain pure 3-Methoxy-4-nitrobenzoic acid.
Safety Information:
- 3-Methoxy-4-nitrobenzoic acid has very limited safety and toxicological information. However, as a chemical substance, appropriate handling and storage measures should be taken to ensure safe use.
-During operation, it is recommended to wear appropriate personal protective equipment, such as laboratory gloves, face masks and protective glasses.
-Avoid contact with skin, eyes or respiratory tract. If contact occurs, rinse immediately with plenty of water and seek medical help.
-Avoid swallowing or inhaling dust-producing substances.
-During storage, it should be kept in a sealed container to avoid contact with oxygen, fire or other flammable substances to prevent fire or explosion.
-For detailed safety operation, please refer to the relevant safety data sheet (MSDS) or consult a professional.
