Cefadroxil-d4 (trifluoroacetate salt)

Cefadroxil-d4 is intended for use as an internal standard for the quantification of cefadroxil (Cay-20365) by GC- or LC-MS. Cefadroxil is a semisynthetic cephalosporin antibiotic. It is active against a variety of Gram-positive and Gram-negative bacteria, including B. anthracis, V. cholerae, and P. multocida strains (MICs = 1, 2, and 4 µg/ml, respectively), among others. Cefadroxil is protective against infection by strains of S. pyogenes, S. pneumoniae, or S. aureus in mice with 50% protective dose (PD50) values of 0.6-2.4, 18-24, and 0.3-29 mg/kg, respectively. Formulations containing cefadroxil have been used in the treatment of a variety of bacterial infections.Formal Name: (6R,7R)-7-[[(2R)-2-amino-2-(4-hydroxyphenyl-2,3,5,6-d4)acetyl]amino]-3-methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
