English Name:3-(5-Nitro-2-furyl)-5-methyl-1,2,4-oxadiazole

CAS No.:63-61-6

Aliases:3-(5-Nitrofuran-2-yl)-5-methyl-1,2,4-oxadiazole, 5-Methyl-3-(5-nitro-2-furyl)-1,2,4-oxadiazole

Molecular Formula:C7H5N3O4

Physical Properties:Yellow or pale yellow crystalline powder, odorless or with a slight characteristic smell. Melting point range: 185-190°C (depending on crystal form). Freely soluble in polar organic solvents such as dimethylformamide and dimethyl sulfoxide, slightly soluble in ethanol and acetone, practically insoluble in water. Sensitive to light and heat; keep in a cool, dark, tightly sealed container.

Uses:This compound is a key intermediate of nitrofuran derivatives, commonly used in the synthesis of antibacterial furan derivatives and bioactive molecules for pharmaceutical and agrochemical applications. In medicinal chemistry, it can serve as a metabolic marker of furazolidone for veterinary drug residue analysis and food safety monitoring. It is also employed in organic synthesis methodology for the construction of functional molecules containing the oxadiazole ring.
