La impureza Diphenyl Sulfide (CAS 139-66-2) | también conocida como Phenyl Sulfide o Diphenyl Thioether | aparece como subproducto en síntesis de compuestos aromáticos con azufre; su presencia afecta pureza | estabilidad y propiedades organolépticas | y puede interferir en análisis cromatográficos por coelución. La identificación y cuantificación se realizan por GC-MS | HPLC con detectores apropiados | NMR y espectrometría de masas. El control en planta requiere optimización de condiciones | purificación por destilación fraccionada | adsorción en carbón activado o recristalización | y límites especificados en especificaciones de calidad. Evaluaciones toxicológicas y validación analítica son críticas para la gestión de este contaminante.
