Description

· Separation type: Liquid Chromatography Mixed-mode SIELC Technologies · HPLC Method for Analysis of Cortisone 21-Acetate on Primesep 100 Column

Cortisone 21-acetate is a synthetic corticosteroid used in the treatment of various inflammatory and autoimmune conditions. It is the acetate ester of cortisone, which increases its stability and bioavailability when administered.

Cortisone 21-acetate is a prodrug of cortisone, which is converted to its active form, cortisol, in the liver. Cortisol exerts its effects by binding to glucocorticoid receptors, which modulate the expression of anti-inflammatory proteins and inhibit the expression of pro-inflammatory proteins.

Cortisone 21-Acetate can be retained, separated and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and phosphoric acid as a buffer. This method allows for detection using UV 200 nm.
