Nature:
1,2-difluoro-4, 5-dimethoxybenzene is a colorless to light yellow liquid with a low boiling point and a high melting point. It is insoluble in water, but can be dissolved in many organic solvents. It has a strong aromatic smell.
Use:
1,2-difluoro-4, 5-dimethoxybenzene is mainly used as an important intermediate in organic synthesis. It can be used in the synthesis of pesticides, pharmaceuticals and other organic compounds. Due to the presence of its BIS-methoxy group, it can also be used as a starting material for the synthesis of dyes and photosensitive materials.
Method:
1,2-difluoro-4, 5-dimethoxybenzene is usually synthesized by fluorination reaction. One common method is to react p-methoxybenzene with chlorofluorous (ClF) followed by methylene chloride (CH2CI2) to produce the desired product.
Safety Information:
1,2-difluoro-4, 5-dimethoxybenzene is an irritating chemical substance that may cause irritation and burns when in contact with skin and eyes, so appropriate safety precautions should be taken during use, for example, wear protective gloves and goggles. In addition, it also has a certain toxicity, should avoid inhalation and intake. During storage and handling, avoid contact with oxidants and strong acids to prevent fire or explosion accidents.
