Slightly hygroscopic, odorless and bitter. Unstable in acid
Purpose: biochemical research. During the extended inhibition period of the peptide transfer step, erythromycin resistance to bacteria is induced by binding to ribosomes to inhibit bacterial protein synthesis. Antibacterial spectrum: gram negative and positive bacteria. It is a macrolide antibiotic.
