1. Product Overview & Technical Specifications

Sulfuryl chloride (CAS 7791-25-5) is a colorless to pale yellow liquid with the molecular formula SO₂Cl₂. It is widely used as a chlorinating and sulfonating agent in organic synthesis.

Technical Parameters

2. Key Applications & Industrial Uses

• Pharmaceuticals: Synthesis of sulfonamides and intermediates.
• Agrochemicals: Production of herbicides and fungicides.
• Polymers: Chlorination of polyethylene and PVC modifiers.
• Dyes: Sulfonation of aromatic compounds.

3. Usage Scenarios & Best Practices

Scenario 1: Chlorination of Aromatic Compounds

In controlled environments, sulfuryl chloride reacts with benzene derivatives at 50-60°C to produce chlorinated aromatics with 85-92% yield.

Scenario 2: Sulfonamide Production

Used in a three-step synthesis process with amines under nitrogen atmosphere, achieving >95% purity in final API intermediates.
