Información del producto

• Nombre: Cefazolin impurity E
• Marca: Biosynth
• Descripción: Cefazolin impurity E (CEF-E) is an impurity of the antibiotic cefazolin. It has been shown to have a redox potential and adsorption mechanism of -0.39 V and 0.14, respectively. CEF-E has been found in urine samples as a result of chemical interactions with nitrogen atoms in the urine. The binding constants for CEF-E are 1.7 x 10^10 M^(-1). The molecular weight of CEF-E is 289.2 g/mol and its nmr spectrum is characterized by peaks at 3.03 ppm and 4.41 ppm, which correspond to C-H protons in the methylene side chain and N-H protons in the pyridine ring, respectively. CEF-E also binds to human liver cells with an inhibitory effect on chloride ion transport, which may be due to its ability to chelate chloride ions with its chelate ring structure.
