Chloramphenicol succinate sodium is the salt prepared from chloramphenicol succinate using the free carboxylic acid of the succinate which ionises and readily forms in weak sodium hydroxide solutions. The sodium salt is the preferred formulation for pharmaceutical applications, providing a more readily soluble product. Chloramphenicol succinate is significantly less active than chloramphenicol but acts as a prodrug, forming chloramphenicol in the presence of succinate dehydrogenase.
Chloramphenicol succinate sodium is soluble in ethanol, methanol, DMF and DMSO.
CAS Number
982-57-0
Molecular Formula
C15H15Cl2N2O8Na
Molecular Weight
445.2
Mechanism of Action
After entering a bacterial cell, chloramphenicol binds to the 50S ribosomal subunit preventing peptide bond formation. Resistance to chloramphenicol may be due to decreased cell permeability or a mutation in the 50S ribosomal subunit.
Storage Conditions
