| Erythromycin EP Impurity D | An acid-catalyzed degradation product of Erythromycin. Erythromycin is a macrolide antibiotic that inhibits bacterial protein synthesis by targeting the 57S ribosomal subunit, blocking the progression of nascent polypeptide chains. Synonyms: Anhydroerythromycin A; Anhydro Erythromycin A; 9-Deoxo-6,12-dideoxy-6,9:9,12-diepoxy-erythromycin; 6,9,12-Anhydroerythromycin A. Grade: >95%. CAS No. 23893-13-2. Molecular formula: C37H65NO12. Mole weight: 715.91. |  |
| Erythromycin EP Impurity E | A decomposition product of the macrolide antibiotic, erythromycin A. Synonyms: 8,9-anhydroerythromycin A 6,9-hemiketal; Erythromycin A enol ether. Grade: >98% by HPLC. CAS No. 33396-29-1. Molecular formula: C37H65NO12. Mole weight: 715.91. | |
| Erythromycin EP Impurity F | A degradation product of erythromycin formed by a complex internal rearrangement of erythromycin A on exposure to neutral to weakly alkaline conditions. It is devoid of antibacterial activity but is an important analytical standard for erythromycin A stability studies. Synonyms: (2R,3R,6R,7S,8S,9R,10R)-7-[(2,6-Dideoxy-3-C-methyl-3-O-methyl-α-L-ribo-hexopyranosyl)oxy]-3-[(1R,2R)-1,2-dihydroxy-1-methylbutyl]-2,6,8,10,12-pentamethyl-9-[[3,4,6-trideoxy-3-(dimethylamino)-β-D-xylo-hexopyranosyl]oxy]-4,13-dioxabicyclo[8.2.1]tridec-12-en-5-one; 8,9-Anhydropseudo-erythromycin A-6,9-hemiketal; EM 701; LY 267108; Pseudo Erythromycin A enol ether; Pseudoerythromycin A enol ether. Grade: >98% by HPLC. CAS No. 105882-69-7. Molecular formula: C37H65NO12. Mole weight: 715.91. | |
