Product Name:Sulfur tetrafluoride
English Name:Sulfur tetrafluoride
CAS No.:7783-60-0
Aliases:Tetrafluorosulfurane
Molecular Formula:SF4
Physical Properties:At normal temperature and pressure, it is a colorless gas with a pungent odor. Melting point approx. -124°C, boiling point -38°C, liquid relative density 1.95. Easily soluble in organic solvents such as benzene. It hydrolyzes violently in water to produce toxic hydrogen fluoride and sulfur dioxide. It has strong thermal stability, being relatively stable at 600°C, but gradually decomposes above 200°C. Highly corrosive, it can corrode glass and most metals.
Uses:Used as a highly efficient selective organic fluorinating agent, capable of selectively fluorinating carbonyl and hydroxyl groups for the synthesis of high-end pharmaceutical intermediates, fluorine-containing pesticides, and liquid crystal materials. In electronics, it serves as an electronic gas for semiconductor plasma dry etching and chemical vapor deposition. It is also used to prepare water/oil repellents, lubricant additives, and compounds such as sulfur hexafluoride.
Technical Specifications:
Purity: ≥99% (electronic gas grade)
Melting point: approx. -124°C
Boiling point: -38°C
Liquid relative density: 1.95 (water=1)
Packaging: 4L or 10L seamless steel cylinders, customizable
