Product Description
Sulfuryl Chloride (SO2Cl2) | Chlorinating Agent
Product Overview
Sulfuryl Chloride (SO2Cl2) is a colorless to pale yellow, highly reactive, and fuming corrosive liquid. Renowned for its exceptional ability to chlorinate and sulfonate organic compounds under mild conditions, it acts as an irreplaceable liquid reagent in the complex synthesis of advanced agrochemicals, pharmaceuticals, and dyestuffs.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we specialize in the safe manufacturing and secure global export of highly reactive, hazardous chemicals. We supply ultra-high-purity Sulfuryl Chloride (≥ 99.0%) engineered strictly for demanding synthesis environments. With our rigorous moisture control and UN-approved anti-corrosive packaging, we guarantee product stability and peak reactivity upon arrival at your chemical plant.
Technical Specifications (COA)
Due to its violent reactivity with water, moisture and free chlorine are strictly minimized to prevent unwanted byproducts. Typical specifications:
| Purity (SO2Cl2) | ≥ 99.0% |
|---|---|
| Appearance | Clear, pale yellow fuming liquid |
| Free Chlorine (Cl2) | ≤ 0.5% |
| Boiling Point | 69.4°C |
| Density (at 20°C) | ~ 1.667 g/cm³ |
Key Applications
- Agrochemical Synthesis: The absolute core reagent for the large-scale production of specialized herbicides, insecticides, and fungicides.
- Pharmaceutical Intermediates: Widely utilized to introduce chlorine or sulfonyl groups into complex aromatic rings for Active Pharmaceutical Ingredients (APIs).
- Dyes & Colorants: Acts as a vital intermediate in the manufacturing of specialty synthetic dyes and organic pigments.
- Polymer Treatment: Used in the chemical treatment of wool to prevent shrinking.
🔬 Superior Selectivity in Chlorination
Compared to using gaseous Chlorine (Cl2), Sulfuryl Chloride offers formulators significantly higher precision and safety. Operating as a liquid, it provides easier stoichiometric control and excellent regioselectivity when chlorinating aliphatic compounds or aromatic rings, leading to higher API yields and reduced waste in your reactors.
Strict Anti-Corrosive DG Packaging
Because SO2Cl2 reacts violently with moisture to form destructive acids, our packaging protocol ensures absolute safety during ocean transit:
- 250 KG / 300 KG Heavy-duty UN-approved Steel Drums with specialized inner anti-corrosive linings (strictly sealed and purged with dry gas).
- ISO TANKS available for large-scale industrial procurement.
⚠️ Safety & Transport Information (Class 8 / 6.1 DG)
- Transport Classification: Classified as Class 8 (Corrosive) with Subsidiary Risk 6.1 (Toxic).
- UN Number: UN 1834 | Packing Group: I (Highest Danger Level)
- Handling Precautions: EXTREME DANGER. Reacts violently with water to form sulfuric acid and HCl gas. Toxic if inhaled. Operators MUST wear full hazmat suits and SCBA. Store in a strictly dry, dedicated DG facility away from water and bases.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
