Infobox references

2-Furoyl chloride is an acyl chloride of furan. It takes the form of a corrosive liquid, which is more irritating to the eyes than benzoyl chloride.[1] 2-Furoyl chloride is a useful pharmaceutical intermediate and is used in the synthesis of mometasone furoate, an antiinflammatory prodrug used in the treatment of skin disorders, hay fever and asthma.[2]

Synthesis

2-Furoyl chloride was prepared in 1924 by Gelissen by refluxing 2-furoic acid in excess thionyl chloride on a water bath.[1]

Applications

2-Furoyl chloride has no major applications but it has been used as a chemical intermediate in the synthesis of various pharmaceuticals; examples include mometasone furoate,[2] fluticasone furoate,[3] diloxanide furoate,[4] Ceftiofur (Excenel),[5] mirfentanil,[6] quinfamide,[7] and diclofurime.[8]
