一般描述

Erythromycin A enol ether (EAEN) is an acidic degradation product of erythromycin A (EA) which is grouped under the macrolide antibiotic class of compounds.

应用

EAEN has been used for the analysis of EAEN as degradation product of EA in honey by ultra-performance liquid chromatography equipped with tandem quadrupole mass spectrometer (UPLC-MS/MS) with positive electrospray ionisation (ESI) operating on multiple reaction monitoring (MRM) mode and in rat′s blood plasma, serum and human urine by high performance liquid chromatography-coulometric assay. It may be used as a reference standard for the detection of EAEN in erythromycin fractions by isocratic LC with evaporative light scattering detection (ELSD) and ion trap MS and in commercial erythromycin samples by LC-MS/MS.
