4-[2-(trimethoxysilyl)ethyl]benzenesulfonyl chloride - Introduction

2-(4-Chlorosulfonylphenyl) ethyl trimethoxysilane, chemical formula C11H19ClO4SSi.

Nature:
1. Appearance: colorless to yellowish liquid.
2. Solubility: Soluble in organic solvents, such as alcohols, ethers, ketones and aromatic hydrocarbons.
3. Melting point: less than -70°C.
4. Boiling point: about 230°C.
5. density: about 1.17 g/cm.
6. stability: stable in neutral and alkaline conditions, but easy to decompose in high temperature, high humidity, sunlight.

Use:
1. As an organic silicon compound, it has strong sulfur affinity and is often used as a crosslinking agent, vulcanizing agent and grafting agent in synthesis.
2. can be used for the synthesis of surfactants to reduce surface tension.
3. can be used for the preparation of functional coatings, sealants and modified materials.

Method:
2-(4-chlorosulfonylphenyl) ethyltrimethoxysilane can be synthesized by coupling 2-chlorosulfonylstyrene and trimethoxysilanol under reaction conditions.

Safety Information:
1. The compound is irritating and should avoid skin and eye contact when in contact.
2. operation should wear protective gloves, protective glasses and protective clothing.
3. should be stored away from fire and oxidant, and in a cool, well-ventilated place.
4. in case of accidental contact or accidental exposure, rinse immediately with plenty of water and seek the help of a doctor.
