A sal dissódica de (S)-ftaloilalanina é uma impureza iônica derivada de ftalimida, associada à química de proteção e desproteção na síntese de peptídeos ou aminoácidos, quando hidrólise incompleta ou rearranjo deixam um resíduo aniônico persistente. Sua fórmula molecular, C11H9NO5.2Na, corresponde a um peso molecular de 235.20 mais 2 x 22.99 g/mol, refletindo a forma de sal dissódico. A identificação e a quantificação em traços são normalmente realizadas por LC-MS/MS, enquanto cromatografia iônica ou métodos HILIC auxiliam a separação de impurezas aromáticas correlatas. Por ser uma espécie polar e não volátil, não é adequada para GC-MS sem derivatização.
