Abstract
Hexacarboxylic acid hexa-amides are described which form new lipophilic magnesium complexes with magnesium ions. The hexa-amides are preferably novel compounds comprising three dicarboxylic acid diamide moieties interconnected to form a non-cyclic, monocyclic, bicyclic, tricyclic or polycyclic structure. Test devices such as test trips or ion-selective members are provided which contain hexacarboxylic acid hexa-amides as the ion-selective component. The test devices have a high selectivity for magnesium ions over alkali metal ions and other alkaline earth metal ions. Selectivity for magnesium ions over sodium and calcium ions permits determination of magnesium concentration in biological materials, including body fluids such as blood serum or whole blood. Magnesium concentration and activity can also be determined in sample solutions having a neutral or slightly acidic pH.
