A impureza (3-chloro-4,5-dihydroxyphenyl)(1,1-dioxidobenzo[d]thiazol-3(2H)-yl)methanone apresenta-se como subproduto de síntese contendo um núcleo benzotiazólico sulfonado ligado a um anel fenólico dicloro-hidroxilado, com elevada capacidade de absorção UV e polaridade moderada que afeta comportamento cromatográfico. Identificação e quantificação requerem métodos validados como HPLC-UV e LC-MS complementados por RMN para confirmar o padrão de substituição. Pode originar-se por oxidação parcial ou acoplamento incompleto e é susceptível a degradação por luz e agentes oxidantes. Sua presença influencia pureza e perfil farmacotóxico, exigindo limites especificados, estratégias de purificação direcionadas e monitorização contínua conforme diretrizes regulatórias.
