Dietilenotriamina (Diethylenetriamine, CAS 111-40-0) como impureza apresenta alta basicidade e reatividade nucleofílica que pode comprometer processos e produtos finais. Mesmo traços promovem desnatação de catalisadores, reações secundárias com isocianatos e agentes eletrofílicos, além de causar amarelamento, odor desagradável e aumento da corrosividade de formulações. Detectável por GC-MS, HPLC com derivatização e titulação ácido-base, sua quantificação é essencial para controle de qualidade. Limites especificados e remoção por destilação fracionada, extração ácida ou adsorventes são práticas comuns para mitigação. Informações sobre estabilidade, ponto de ebulição e solubilidade orientam avaliação de risco e procedimentos de purificação.
