Analysis of Corticosteroids

This simple isocratic Method demonstrates good separation of two similar synthetic Glucocorticoids.  This analysis for corticosteroids may serve well for quantitation in pharmaceutical preparations.  This Method would easily translate to LCMS.

1. Prednisone
2. Dexamethasone
