Impureza 2′-Chloroacetanilide (CAS 533-17-5) frequentemente ocorre como subproduto de reações de acetilação ou cloração durante síntese orgânica e pode resultar de degradação térmica ou hidrólise parcial. Sua identificação e quantificação requerem métodos analíticos sensíveis como HPLC com detector UV | GC-MS e LC-MS/MS | complementados por RMN e espectroscopia IR para confirmação estrutural. A presença acima de níveis traço compromete a pureza do material | estabilidade e perfis toxicológicos | implicando risco regulatório. Estratégias de controle incluem otimização do processo | purificação por cromatografia ou recristalização | monitoramento em processo e especificação de limites aceitáveis para garantir conformidade e qualidade.
