Sulfapyridine Usage And Synthesis
Chemical PropertiesWhite to Off-White Solid
UsesUsed in treatment of dermatitis herpetiformis; antibacterial.
Usesantibacterial, dermatitis herpetiformis therapy
DefinitionChEBI: A sulfonamide consisting of pyridine with a 4-aminobenzenesulfonamido group at the 2-position.
General DescriptionOdorless or almost odorless white or yellowish-white crystalline powder. Very slightly bitter taste. Aqueous solution is neutral.
General DescriptionSulfapyridine’s plasma half-life is 9 hours.This compound is a white, crystalline, odorless, and tastelesssubstance. It is stable in air but slowly darkens on exposureto light. It is soluble in water (1:3,500), in alcohol(1:440), and in acetone (1:65) at 25°C. It is freely soluble indilute mineral acids and aqueous solutions of sodium andpotassium hydroxide. The pKa is 8.4. Its outstanding effectin curing pneumonia was first recognized by Whitby; however,because of its relatively high toxicity, it has been supplantedlargely by sulfadiazine and sulfamerazine. Severalcases of kidney damage have resulted from acetylsulfapyridinecrystals deposited in the kidneys. It also causes severenausea in most patients. Because of its toxicity, it is usedonly for dermatitis herpetiformis.
Sulfapyridine was the first drug to have an outstandingcurative action on pneumonia. It gave impetus to the studyof the whole class of N1 heterocyclically substituted derivativesof sulfanilamide.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileSulfapyridine is an amino acid. Slowly darkens on exposure to light . Soluble in both acidic and basic aqueous solutions
Fire HazardFlash point data for Sulfapyridine are not available; however, Sulfapyridine is probably combustible.
Safety ProfileModerately toxic by intraperitoneal and intravenous routes. Slightly toxic by ingestion. Experimental reproductive effects. Human mutation data reported. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of NO, and SOx.
Purification MethodsCrystallise sulfapyridine from 90% acetone and dry it at 90o. Its solubility in Me2CO, EtOH and H2O is 1.5%, 0.22% and 0.02%, respectively. [Winterbottom J Am Chem Soc 62 160 1940, Beilstein 22 III/IV 3978.]
