Common Spelling & Search Variants

In industrial chemical procurement across India, buyers and plant managers search for this fuming reagent using various names. Whether your plant specifies Sulfuryl Chloride (standard IUPAC), the UK/Commonwealth variant Sulphuryl Chloride, or common spelling typos like Surphuryl Chloride, Sulphurl Chloride, or Sulfury Chloride, they all refer to the same high-purity chlorinating reagent (CAS No. 7791-25-5, SO2Cl2) manufactured and supplied by Shree Vinayak Chemex.

Sulfuryl Chloride vs Thionyl Chloride, PCl5 & Other Alternatives

As a selective chlorinating agent, Sulfuryl Chloride (SO2Cl2) offers unique benefits compared to Thionyl Chloride (SOCl2, CAS 7719-09-7) and Phosphorus Pentachloride (PCl5). While Thionyl Chloride excels at acyl chloride conversions, Sulfuryl Chloride is the industry standard for selective side-chain chlorination of alkanes and alkylbenzenes. Its gaseous by-products (SO₂ and Cl₂) escape easily from the reaction mixture, facilitating simpler purification pipelines than PCl5 or fuming sulfuric acid (Oleum).

RFQ questions

What should I share for a faster quote?

Target quantity, destination, packing preference, expected timeline, and any internal documentation requirements.

Which documents can be discussed before purchase?

SDS support, COA requirements, batch traceability, packing details, and dispatch paperwork can be aligned with the sales team.

Why is the page focused on one product?

Sulfuryl Chloride needs a specific conversation around identity, moisture control, packing, and hazardous chemical dispatch.

How do you ship Sulfuryl/Sulphuryl Chloride in Mumbai and Gujarat?

As leading suppliers, we serve the industrial GIDCs and MIDCs (including Tarapur MIDC, Kupwad Sangli MIDC, Saykha GIDC, Vapi GIDC, Ankleshwar GIDC, and Dahej GIDC) with specialized, hazard-controlled logistics and compliant packing such as 300kg composite drums or HDPE carboys.

What is the price of Sulfuryl/Sulphuryl Chloride per kg in India?

The price depends heavily on the purity grade (e.g., high-purity 99% min), volume (bulk commercial scale vs laboratory reagent scale), packaging requirements, and dispatch schedules. Contact our sales office in Opera House, Mumbai for current competitive quotes.

Do you supply other fuming reagents like Thionyl Chloride or Oleum?

No, Shree Vinayak Chemex focuses exclusively on manufacturing high-purity Sulfuryl Chloride (SO2Cl2). However, we help buyers compare it to other sulphur/chlorine reagents (like Thionyl Chloride CAS 7719-09-7, Oleum CAS 8014-95-7, or Chlorosulphonic Acid CAS 7790-94-5) to optimize reaction yields and safe handling parameters.

Do you support common phonetic spellings like Surphuryl Chloride?

Yes. Whether you search for the standard American spelling (Sulfuryl Chloride), the British/Commonwealth variant (Sulphuryl Chloride), or phonetic typos (Surphuryl Chloride, Sulphurl Chloride, Sulfury Chloride), they all represent the same chemical reagent with CAS number 7791-25-5 and formula SO2Cl2.
