Thionyl Tetrafluoride , CAS 13709-54-1 , is the sulfur oxyfluoride represented as SOF4 or F4OS, with molecular weight 124.06 g/mol. It is distinct from thionyl fluoride, SOF2, CAS 7783-42-8. Commercial review should confirm assay, fluorinated and moisture-derived impurities, supply form, cylinder and valve specification, pressure or fill basis, analytical method and safe connection requirements. A conventional liquid chemical drum is not an appropriate default package for this material.

Applications and grade selection
Thionyl Tetrafluoride is a specialty fluorine material for controlled professional gas-phase, fluorination or sulfur oxyfluoride research. Application claims must be tied to a defined process, compatible gas system and qualified impurity profile rather than a generic industrial-grade statement.
- Confirm whether the offer is compressed gas, liquefied material or another documented supply form.
- Agree assay, impurity species, moisture basis, detection limits and sampling method.
- Review cylinder, valve, regulator, line materials and abatement requirements before ordering.
Storage and handling
Keep the approved pressure package secured in a controlled, ventilated area under the current SDS. Protect the valve, prevent moisture ingress and separate the package from incompatible materials, heat and unauthorized handling.
Safety, documentation and procurement
Only trained personnel with a reviewed gas-handling procedure, compatible equipment, leak detection and emergency controls should handle this material. Procurement must confirm destination rules, package return terms, transport classification and documentation.
FAQ - Technical & Supply Chain
-
Q:
Is Thionyl Tetrafluoride the same gas as Thionyl Fluoride?
A: No. Thionyl Tetrafluoride is SOF4, CAS 13709-54-1, whereas Thionyl Fluoride is SOF2, CAS 7783-42-8. Confirm the formula, CAS number and a gas-analysis identity result because the shortened name sulfur oxyfluoride can otherwise cause an incorrect match. -
Q:
Which details are required for a Thionyl Tetrafluoride gas inquiry?
A: Specify purity, moisture and relevant fluorinated or non-condensable impurities, required quantity, cylinder size, fill or pressure basis, valve and connection standard, destination and return terms. Review the batch analysis and current SDS before approving the cylinder and gas-handling system.
