4-乙基苯磺酰氯 - Introduction
The chemical formula is C8H9ClO2S, which is an organic compound. Its nature is as follows:
1. Appearance: colorless liquid with pungent odor.
2. Solubility: It can be dissolved in many organic solvents, such as ethers, alcohols and esters.
3. Reactivity: It has electrophilic substitution and can react with many nucleophiles, such as alcohols, amines, water, etc.
The main uses of the pill are:
1. Synthetic pesticides: it can be used as an intermediate for the synthesis of pesticides containing benzenesulfonyl chloride functional groups of pesticides, such as acetochlor, two acetochlor and so on.
2. Pharmaceutical field: It is widely used in the preparation of pharmaceutical intermediates and active substances, such as non-steroidal anti-inflammatory drugs containing sulfonyl chloride functional groups.
The preparation method is generally synthesized by reacting benzene sulfonyl chloride with an ethylating agent (such as ethyl chloride).
When using and storing the following safety information:
1. Avoid Contact: avoid skin contact and inhalation. Wear appropriate personal protective equipment such as chemical protective clothing, goggles and respirators.
2. Fire and explosion-proof: it is flammable, away from fire sources and other flammable materials.
3. Storage: Store in a cool, dry and well-ventilated place, away from oxidants and fire sources.
4. Waste Disposal: Disposal of waste in accordance with local regulations and do not dump or discharge it.
Please note that the information provided above is for reference only. Please understand the relevant safety information in detail before using chemicals and follow the corresponding operating regulations.
