Impureza 1-Naphthylacetamide (CAS 86-86-2) descrita como subproduto aromático recorrente em sínteses de derivados naphthílicos | apresenta perfil químico e analítico crítico para controle de qualidade; caracteriza-se por sinais aromáticos sobrepostos em RMN proton e carbonila amida em espectros IR | massa molecular confirmada por LC-MS | e boa absorção em UV que facilita detecção por HPLC-UV. Prováveis impurezas correlatas incluem isômeros posicionalmente substituídos | subprodutos de N-desacilação e solventes residuais. É moderadamente estável mas susceptível a oxidação em condições agressivas. O monitoramento por HPLC em fase reversa | acoplado a MS e ensaios de pureza por cromatografia | é recomendado para controle e quantificação.
