| Cefuroxime Axetil Delta-3 | Δ2-Cefuroxime axetil is an oral prodrug of cefuroxime, a second-generation cephalosporin antibiotic. This compound inhibits bacterial cell wall synthesis by targeting penicillin-binding proteins (PBPs), making it effective against a broad spectrum of Gram-positive and Gram-negative bacteria. It is commonly prescribed for respiratory, urinary tract, and skin infections. Synonyms: 1-Acetoxyethyl (6R,7R)-3-((carbamoyloxy)methyl)-7-((Z)-2-(furan-2-yl)-2-(methoxyimino)acetamido)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-3-ene-2-carboxylate; 5-Thia-1-azabicyclo[4.2.0]oct-3-ene-2-carboxylic acid, 3-[[(aminocarbonyl)oxy]methyl]-7-[[(2Z)-2-furanyl(methoxyimino)acetyl]amino]-8-oxo-, 1-(acetyloxy)ethyl ester, (6R,7R)-; 5-Thia-1-azabicyclo[4.2.0]oct-3-ene-2-carboxylic acid, 3-[[(aminocarbonyl)oxy]methyl]-7-[[2-furanyl(methoxyimino)acetyl]amino]-8-oxo-, 1-(acetyloxy)ethyl ester, [6R-[6α,7β(Z)]]-; Cefuroxime Axetil Impurity A (Delta 3-Isomer); Cefuroxime Axetil EP Impurity A; Cefuroxime Axetil Impurity A (EP); Δ2-Cefuroxime axetil; delta3-Cefuroxime axetil. Grade: 95%. CAS No. 123458-61-7. Molecular formula: C20H22N4O10S. Mole weight: 510.47. | |
| Di(cefuroxime Ethyl) Ether | Di(cefuroxime Ethyl) Ether is an impurity of Cefuroxime which is an antibaterial agent. Synonyms: Cefuroxime axetil dimer; Cefuroxime 1,1'-Oxydiethanol Diester Dimer Impurity (Diastereomeric Mixture). CAS No. 1202925-10-7. Molecular formula: C36H38N8O17S2. Mole weight: 918.86. | |
| (E)-Cefuroxime axetil | (E)-Cefuroxime axetil is the (E)-isomer of cefuroxime axetil, a prodrug form of the second-generation cephalosporin antibiotic cefuroxime. The E configuration refers to the stereochemistry of the oxime group on the β-lactam core, which is in the trans orientation. This isomer is the therapeutically active form, contributing to its antibacterial efficacy. Cefuroxime axetil improves the oral bioavailability of cefuroxime by utilizing the acetoxyethyl ester as a prodrug, which is hydrolyzed in vivo to release the active drug. It acts by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs). This compound is effective against a wide range of Gram-positive and Gram-negative bacteria and is commonly used to treat respiratory tract infections, urinary tract infections, and skin infections. Synonyms: 1-Acetoxyethyl (6R,7R)-3-((carbamoyloxy)methyl)-7-((E)-2-(furan-2-yl)-2-(methoxyimino)acetamido)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate; Cefuroxime Axetil E-Isomer Impurity 1; 1-(Acetyloxy)ethyl (6R,7R)-3-[[(aminocarbonyl)oxy]methyl]-7-[[(2E)-2-(2-furanyl)-2-(methoxyimino)acetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate; 5-Thia-1-azabicyclo[4.2.0]oct-2-ene-2-c. Grade: ≥95%. CAS No. 97232-96-7. Molecular formula: C20H22N4O10S. Mole weight: 510.47. | |
