Sulfuryl fluoride appears as a colorless odorless gas. Shipped as a liquefied gas under its own vapor pressure. Noncombustible. Heavier than air. Very toxic by inhalation. Contact with the unconfined liquid can cause frostbite. Prolonged exposure to heat can cause containers to rupture violently and rocket. Used as an insecticide fumigant in wooden structures to control termites and wood-infesting beetles, and used in organic synthesis.

Identification of fluorosulfate and sulfate in blood and urine suggests that SO(2)F(2) is hydrolyzed to fluorosulfate, with release of fluoride, followed by further hydrolysis to sulfate and release of the remaining fluoride.
4 jugular vein cannulated Fischer 344 male rats and 4 non-cannulated males per group received nose-only inhalation exposure (4 hours) to 35S-Sulfuryl Fluoride at 30 and 300 ppm. Additionally, 18 non-cannulated males per group were exposed (4 hours, nose-only inhalation) to non-radiolabelled sulfuryl fluoride at 30 and 300 ppm and 8 non-cannulated males served as a vehicle control (dry, compressed air) group. Time-weighted actual exposure concentrations over the 4-hour treatment period with 35S-sulfuryl fluoride were 28.4 ppm (0.26 uCi/L of atmosphere) and 274 ppm (2.8 uCi/L of atmosphere) at the 30 ppm and 300 ppm nominal levels respectively. Values were 31.2 ppm and 312 ppm at 30 ppm and 300 ppm respectively for non-radiolabelled sulfuryl fluoride exposures. Venous blood samples (0.15 mL) were collected from cannulated rats at 0.25, 0.5, 1, 2, 3, and 4 hours during inhalation exposure and 0.5, 1, 2, 4, 6, 12, 24, 36, 48, 72, 96, 120, and 168 hours post-exposure. 3 animals per group exposed to non-radiolabelled sulfuryl fluoride were sacrificed after 2 and 4 hours of exposure and 2, 4, 8, and 20 hours post exposure to measure fluoride ion content in plasma, brain, and kidney. Additionally, fluoride ion content was determined in plasma, brain, and kidney of 2 control rats per group at the beginning and end of exposure and 4 and 8 hours post-exposure. No radioactivity was detected in expired air of the 300 ppm group animals at 24 hours post exposure, therefore, collection of expired air was not continued for the remaining sampling intervals of the group and not performed at all for 30 ppm animals. ... Metabolites Identified Following 35S-Sulfuryl Fluoride Exposure. Two radiolabeled metabolites, sulfate and fluorosulfate, both hydrolysis products of sulfuryl fluoride, were identified in whole blood and urine. ... Metabolic release of fluoride ions was proposed as the cause of toxicity in sulfuryl fluoride exposure ... therefore, quantification was performed. Elevated levels of fluoride ion were detected in urine, plasma, kidney, and brain during and after exposure to non-radiolabelled sulfuryl fluoride. Most returned to background levels at varying times post-exposure.
... It was shown that termites fumigated with a nonlethal concentration of (35)S-sulfuryl fluoride excreted inorganic sulfate, indicating that fluoride had been released. Then, using the labeled metabolic pool technique, separate studies of termites prefed sodium (14)C-acetate or on (32)P-phosphate showed that fumigated termites exhibited a spectrum of metabolic changes characteristic of fluoride toxicity.

Solutions of fluoride salts are rapidly and almost completely absorbed from the gastrointestinal tract, probably by simple diffusion ... Less than 10% of the ingested fluoride is excreted in the feces, but the proportion varies with circumstances ... The simultaneous presence of strongly fluoride-binding ions, especially calcium ions, will reduce the absorption of fluoride ... In patients ingesting aluminum-containing antacids, fluoride absorption decr to about 40%, and the retention decr to nil. /Fluorides/
In the industrial environment, the respiratory tract is the major route of absorption of both gaseous and particulate fluoride. Hydrogen fluoride being highly soluble in water is rapidly taken up in the upper respiratory tract ... Depending on their aerodynamic characteristics, fluoride-containing particles will be deposited in the nasopharynx, the tracheo-bronchial tree and the alveoli ...

Herein, we report a new method for the one-pot syntheses of sulfonyl fluorides. Addition of an alkyl, aryl, or heteroaryl Grignard to a solution of sulfuryl fluoride at ambient temperature affords the desired sulfonyl fluorides in 18-78% yield. Furthermore, this method is applicable for in situ sequential reactions, whereby the Grignard reagent can be converted to the corresponding diarylsulfone, sulfonate

Acid fluorides, for example carboxylic acid fluorides and sulfuryl fluoride are produced by reacting the corresponding acid chlorides with hydrogen fluoride adducts of ammonium fluoride or amine hydrofluorides (which act as a catalyst or as a fluorination agent). Consumed HF adducts may be regenerated with HF.
