N-Nitroso Caffeidine (CAS 145438-96-6) é uma impureza nitrosada relevante identificada em linhas de síntese e em produtos farmacêuticos que contenham precursores amínicos. A presença pode ocorrer por nitrosação durante etapas de reação ou por degradação durante armazenamento | exigindo monitoramento analítico rigoroso. Métodos sensíveis como LC-MS/MS e GC-MS com enriquecimento por SPE são recomendados para quantificação em níveis traço. Avaliação toxicológica | estabelecimento de limites de especificação e estratégias de mitigação como controle de agentes nitrosantes e condições de processamento são essenciais para garantir conformidade regulatória e integridade do perfil de impurezas.
