Impureza Ácido Aminobenzoico (1019803 | CAS 150-13-0) é um contaminante crítico em matérias-primas que pode afetar desempenho analítico e qualidade do produto final. Caracteriza-se por perfil cromatográfico semelhante ao composto principal | solubilidade moderada em solventes polares e estabilidade relativa sob condições neutras | mas suscetível à oxidação e descarboxilação sob calor e luz. Monitoramento por HPLC com detecção UV | LC-MS e GC após derivatização garante identificação e quantificação precisas. Especificações típicas incluem limites de impureza individual e total | validação de métodos e estratégias de purificação para redução abaixo de limites regulamentares | além de recomendações de armazenamento anidro e condições de transporte controladas.
