Ethyl 5-Methylisoxazole-4-carboxylate (CAS 51135-73-0) é uma impureza heterocíclica frequentemente monitorada em matérias-primas e intermediários devido ao seu potencial impacto no perfil de pureza e nas propriedades fisicoquímicas do produto final. Caracteriza-se por massa molecular e sinais específicos por espectrometria de massas e ressonância magnética nuclear | e é detectável por técnicas cromatográficas como HPLC e GC acopladas a detectores espectrométricos. A presença desta impureza pode afetar rendimento analítico | estabilidade e requisitos de segurança | exigindo estratégias de controle analítico e limites de especificação baseados em estudos de risco e toxicidade. Fornece dados críticos para conformidade regulatória e garantia de qualidade.
