La impureza 21-Acetoxy-11beta-hydroxypregna-1 | 4 | 16-triene-3 | 20-dione (CAS 3044-42-6) presenta un núcleo pregnano conjugado con grupos cetona | hidroxilo y acetoxi que condicionan su polaridad y perfil cromatográfico | favoreciendo retenciones intermedias en HPLC de fase inversa y absorción UV por el sistema trieno. Su presencia indica reacciones incompletas de acetilación o procesos de degradación como deshidratación u oxidación del 11beta-hidroxilo | y puede controlarse mediante LC-MS para identificación de masa | NMR para confirmación estructural y ensayos de estabilidad forzados. La cuantificación precisa en el perfil de impurezas es crítica para la evaluación de seguridad y pureza del principio activo.
