Erythromycin, a macrolide antibiotic

As this compound lacks chromophores, it typically requires derivatization for use in UV detection.  In this method, we retain excellent peak shape without the need for these pre-column derivatization steps saving time and resources.

RSD values (less than 0.5%) demonstrate the consistent and reliable retention, as shown in the 10 injections overlay below.
