Prednisolone 17-acetato (CAS 52628-64-5) é uma impureza orgânica relevante em processos de síntese e formulação de derivados de prednisolona. Originada por acetilação incompleta ou por reações secundárias durante a esterificação | esta impureza pode comprometer o perfil de pureza | a estabilidade e propriedades reológicas do produto final. Sua identificação e quantificação exigem técnicas analíticas robustas como HPLC com detecção UV | LC-MS para confirmação de massa e RMN para elucidação estrutural. O controle passa por otimização de processo | purificação cromatográfica e estabelecimento de limites conforme as diretrizes ICH Q3A Q3B. Monitoramento contínuo e validação de método são imprescindíveis.
