Ammonium furan salt, also known as methylene imine ammonium furan acetate, is an important intermediate in the synthesis of cefuroxime side chain. Cefuroxime, as the second generation of cephalosporin broad-spectrum antibiotics, is widely used in clinical practice. It can be used for respiratory tract infection caused by sensitive bacteria, as well as for urinary tract, skin and gonorrhea. It can simulate staphylococcus aureus, gram-positive coccus and gram-negative bacilli.
