2,5-Dimethoxybenzenesulfonyl chloride - Introduction
2, chloride(2, chloride) is an organic compound with the chemical formula C8H9ClO3S.
Nature:
-Appearance: Colorless or light yellow liquid
-Solubility: Soluble in organic solvents such as ether, dichloromethane and benzene, insoluble in water
-Melting point: About 20-25 degrees Celsius
-Boiling point: about 125-130 degrees Celsius
-Toxicity: The compound has certain toxicity, so you need to pay attention to safe operation during use.
Use:
2. chloride is commonly used in organic synthesis and is mainly used as a chlorosulfonylation reagent. It can react with other compounds to form acid chloride derivatives, such as esters, amides and acid chlorides. It can also be used in the preparation of drugs, dyes, rubber auxiliaries and other organic chemistry fields.
Method:
2. The preparation of chloride is usually obtained by reacting benzene sulfonyl chloride with 2,5-dimethoxybenzene alcohol. Specific steps are:
1. Add benzenesulfonyl chloride to a solvent (such as dichloromethane or benzene);
2. Slowly add 2,5-dimethoxyphenyl alcohol while stirring the reaction mixture;
3. React at room temperature for several hours until the reaction is completed;
4. Filter the precipitate and wash to remove impurities.
Safety Information:
- 2, chloride is irritating. Wear protective gloves and glasses to avoid contact with skin and eyes.
-Store in a sealed container and keep away from high temperature and fire sources.
-use to ensure good ventilation, avoid inhalation of its steam.
-Pay attention to prevent contact with oxidants and strong bases to avoid dangerous reactions.
-Please pay attention to personal protection and laboratory safety procedures when using.
